First you need a magnet to move. An atom is essentially a magnet. So when an atom moves past another atom it must therefore induce a change in the others magnetic field And vice versa. Move many atoms in the same direction past a smaller amount that arent moving then one will induce a current in the latter. The direction of the induced current can be deduced by refering to flemings law. The earth displays this in its magnetic field. And researchers have discovered that any moving fluid conductor when rotated will induce a current in the rotating fluid conductor itself. Something you pretend... cannot happen. You ask me to supply the references? Heres a few ... ****** By eavesdropping on earthquake vibrations passing through the globe's innards, seismologists have discovered that Earth's solid core is a solo dancer, spinning separately from the rest of the planet. Earth's metallic core consists of a solid iron sphere, about three- quarters of the size of the moon, sitting within an outer shell of roiling liquid iron. Hidden beneath 2,600 kilometers of rock, the core has remained the most cryptic realm of our planet. Some theorists have argued that electromagnetic forces inside Earth should cause the core to spin separately from the planet's outer layers. Others have hypothesized that the core should spin in synchrony with the mantle and the crust. Xiaodong Song and Paul G. Richards of the Lamont-Doherty Earth Observatory in Palisades, N.Y., have found that the inner core rotates in the same direction as the rest of the planet but about 1 degree per year faster. They report their observation in the July 18 Nature. The surface of the core, at its equator, is moving about 20 km per year relative to the liquid outer core. "That's 100,000 times faster than the types of motion we normally associate with properties of the solid Earth," says Richards. In contrast, the continents creep across Earth's surface at only a few centimeters per year. Song and Richards embarked on their research after a computer simulation at Los Alamos (N.M.) National Laboratory predicted that Earth's core should spin 1 degree to 2 degrees faster per year than other parts of the planet. Gary A. Glatzmaier of Los Alamos says he was surprised that Song and Richards could actually observe the core's rotation. "We were really excited to hear that they had found this," says Glatzmaier. The Lamont-Doherty scientists could not have detected the core's movement without the help of recent discoveries about inner Earth. Ten years ago, seismologists found that earthquake vibrations passing through the solid core travel at different speeds, depending on their direction--a property called anisotropy. Waves go most slowly in the plane of the equator and most quickly when heading poleward. In the last 4 years, seismologists have uncovered evidence that the grain is skewed slightly from an exact north-south alignment. The axis of anisotropy--corresponding to the fastest direction for seismic waves--tilts about 10 degrees from Earth's axis of rotation. Song and Richards realized that this axis of anisotropy, which currently points toward Siberia, should shift over time if the core rotates separately. To test the idea, they pulled out old recordings made in central Alaska of earthquakes that occurred in the South Atlantic. Some of the seismic waves from the southern quakes passed through the inner core on their way north. Comparing the old records with newer earthquake recordings, the scientists determined that seismic waves now take about 0.3 second less to complete the journey than they did during the 1960s. This finding suggests that the core has rotated in a way that speeds seismic waves heading from the South Atlantic to Alaska. The Lamont-Doherty scientists and other teams of researchers are now examining different seismic records to validate the discovery and to measure the core's rotation with more precision. "I think this is one of the most exciting things to happen in the last several years in deep-Earth studies," says Kenneth C. Creager of the University of Washington in Seattle. ***** | What makes you think that when | I say.."a moving magnet induces a current"" | I actually mean .." a moving magnet does not induce | a current".. ??!

You are trying not to understand on purpose here. The induced current is created by the relative motion between the outer part of the liquid core and the inner part. Here is a description of the earths inner dynamo by another online source . Although they make slightly different assumptions about what the exact mechanism is, they still use the assumption that the inner and outer parts of the liquid core act as a dynamo. Maybe their description will help you understand how a dynamo mechanism can be attributed to earths emf.... ****** -Gary A. Glatzmaier of the Institute of Geophysics & Planetary Physics at Los Alamos National Laboratory is one of the pioneers in modeling the earth's core provides this response: "This effect that Roberts and I found in our simulation is analogous to the way in which a synchronous electric motor works, with the inner core acting like the rotor. The jet streams in the fluid outer core result from thermal and compositional buoyancy forces, Coriolis forces, pressure gradients and magnetic Lorentz forces. Hence, the super-rotation of the inner core is really neither a pure cause nor a pure effect of the magnetic field. The situation is much more intricate: the inner core rotation, the fluid flow, the magnetic field, and the thermal and compositional distributions all have complicated nonlinear feedbacks on one another. ******* Heres another onlinbe description you may find enlightening... ****** The Dynamo Effect The simple question "how does the Earth get its magnetic field?" does not have a simple answer. It does seem clear that the generation of the magnetic field is linked to the rotation of the earth, since Venus with a similar iron-core composition but a 243 Earth-day rotation period does not have a measurable magnetic field. It certainly seems plausible that it depends upon the rotation of the fluid metallic iron which makes up a large portion of the interior, and the rotating conductor model leads to the term "dynamo effect" or "geodynamo", evoking the image of an electric generator. **** My guess is that venus doesnt have a rotating liquid core. That would explain why it doesnt seem to have a magnetic field. And heres a description of the fluid rotating conductor experiment that shows that a rotating conductor can sustain without outside assistance, a magnetic field. Contrary to what you believe is possible.I think the term you dont understand is "self sustaining feedback". ****** Phys. Rev. Lett. 98, 044502 (issue of 26 January 2007) Title and Authors 30 January 2007 Molten Metal Magnet VKS Collaboration Causing a stir. When filled with molten sodium and stirred at up to 26 revolutions per second, this tank generates a magnetic field--similar to the way the Earth's core creates a field. Previous experiments controlled the flow more carefully and avoided turbulence, so they were less like the Earth's core. The Earth generates a magnetic field from the flow of molten metal in its core. Lab experiments have generated fields in a similar way, and in the 26 January Physical Review Letters, researchers report that they can create the self-sustaining magnetic field even when the flow is highly turbulent. The new experiment is a more realistic simulation of Earth's dynamo than previous experiments because the fluid flows freely in a large tank instead of being channeled into prescribed patterns with baffles or tubes. The new design should help researchers better understand the factors that give rise to magnetic fields in planets and stars. It's easy to create a magnetic field by using a battery to force an electric current through a loop of wire. But Earth's core, a rotating mix of iron and nickel with internal flows driven by the passage of heat, has no battery and no wires. Instead, it creates magnetism by means of self-sustaining feedback. Liquid metal moving through a magnetic field generates a current, similar to that induced in the moving coil of an electric generator. That current in turn generates the magnetic field. This "self-generation" mechanism can dramatically amplify the small, random fields that always exist in magnetic materials. To do this, though, the flow must be both complex, mixing up the longitudinal and latitudinal directions, and rapid, "tangling up" magnetic field lines faster than they can untangle. To demonstrate self-generation in the lab, two teams in 2000 forced liquid sodium into complex but non-turbulent flows using physical barriers that deflected the fluid along precisely defined paths. Now the French VKS collaboration--which includes the École Normale Supérieure (ENS) institutes in Paris and Lyon and the Atomic Energy Commission (CEA) in Saclay--has created a self-generating magnetic field with a less contrived flow. They placed disks, equipped with curved vanes, at each end of a half-meter long cylindrical tank filled with liquid sodium. Rotation of these "propellers" in opposite directions at up to 26 revolutions per second created a turbulent flow that generated a magnetic field. The field only appeared when the propellers were made of iron, which modifies the field near its surface. Compared to the previous experiments, "the flow is less constrained geometrically," says team member Stéphan Fauve of the ENS in Paris, although he admits it's not as free as in Earth's core or in other planets, stars, or galaxies with magnetic fields. The spontaneous field appeared when the average flow speed throughout the liquid was surprisingly low. Researchers expected a much higher speed would be needed--perhaps impractically high--because other experiments suggested that turbulence would increase the "untangling" rate for field lines and destroy the dynamo effect. (The Earth's dynamo is turbulent but also operates at a much higher effective speed.) This is "the first time a magnetic field is self-generated by a fully turbulent flow with turbulent fluctuations as large as the mean flow," says Fauve. "There is a real advance here," says Cary Forest of the University of Wisconsin at Madison, who also explores magnetic fields arising in turbulent sodium flow. But he notes that the turbulent eddies in this experiment are almost as big as the experimental cell itself, whereas the eddies of molten metal that give rise to Earth's magnetism are much smaller than the core. "It would be interesting in the future to have an experiment where one had turbulence at small scales driving a magnetic field at large scales," he says. ****** Amazing stuff isnt it? Earth can quite literally pick itself up by its bootstraps after all,and generate a magnetic field. In fact its not that magical. Because to create a emf one only needs force moving a conductor that moves relative to another conductor to create an emf. As the experiments show in the reference Ive quoted above. The force is the earths gravitational slingshot around the sun and ultimately its own rotation around its own axis. The different moving conductors are supplied by the liquid core moving at different relative speeds. Put these together and you have an emf generated. If you dont believe its possible.. Then explain why the above french team managed to generate a emf purely from a rotating liquid conductor without any external input? | | a magnet south pole first downwards | | into the top end,. the current in the solenoid | | flows from top to bottom. The same occurs if the magnet | | is reversed so that its north pole enters the top end of | | the solenoid first and moves downwards. | | But if you move the magnet either north or south pole first | | upwards from the bottom of the solenoid then the current is | | reversed in the solenoid. This is what any reference claims | | is observed. It is this effect that I use to explain | | how the current is induced in the liquid core. | | Yes, but the solenoid doesn't induce any voltage without you | applying a force to make it move. | Well Im glad you agree with me now that a moving magnet | will induce a current. I've known how generators work since I as a teenager riding a bicycle with lamps to light. Same method as the earths core. Except the inner and outer parts of the liquid core dupicate the moving parts of your bike lamp generator. And the force in your feet moving the wheels duplicates the gravitational force from the sun and the earths force of the earths own mass spinning on its axis. | So what is the force that rotates the core relative | to the mantle? | First of all it is accepted by the scientific | community that the earths core DOES rotate relative to the mantle Second of all it is NOT accepted by the scientific community that the Earth's core rotates relative to the mantle, you made that up. Next time try google for reference before you pretend I make things up. Heres a few references that clearly show that it is YOU who makes things up... ****** 1)Recent evidence has suggested that the inner core of Earth may rotate slightly faster than the rest of the planet.[8] In August 2005 a team of geophysicists announced in the journal Science that, according to their estimates, Earth's inner core rotates approximately 0.3 to 0.5 degrees per year relative to the rotation of the surface. 2)Xiaodong Song and Paul G. Richards of the Lamont-Doherty Earth Observatory in Palisades, N.Y., have found that the inner core rotates in the same direction as the rest of the planet but about 1 degree per year faster.

Waves go most slowly in the plane of the equator and most quickly when heading poleward. To explain the differences in speed, researchers proposed that the iron crystals in the inner core have a distinct orientation, like the grain in wood. Waves moving along this crystalline grain travel faster than those going against it. In the last 4 years, seismologists have uncovered evidence that the grain is skewed slightly from an exact north-south alignment. The axis of anisotropy--corresponding to the fastest direction for seismic waves--tilts about 10 degrees from Earth's axis of rotation.

If so then why have the above researchers and many others decided it does rotate seperately? What is the force that rotates the core relative to the mantle? | Ive cited one source in my initial post to clarify that its | not me imagining this.Here it is again.. | Song, Richards 2005 Check it out on google . No. Either a give me a specific reference or shut up, I'm not doing research on songs. Ive now given you numerous references to show that many researchers now agree that earths mantle moves relative to its core, that earths liquid core moves at different relative speeds and that this can create a dynamo effect that is also observed in labarotory experiment to spontaneously generate an emf. | So Ive responded to this observed fact No you haven't and there is no observed fact. Answer the question. What is the force that rotates the core relative to the mantle? The same force that rotates earth around its own axis.

Basic questions: As far as I see almost all theoretical models, not just mine, can only speculate on how exactly the field is induced and what properties or constituents the liquid and solid cores have. In fact all the theoretical models Ive read cannot even explain how the field seeds itself. They resort to an imaginary unexplained spontaneous appearance of a seed field. Thats part of the reason why I posted my model here. I can explain how the field is generated and sustained by using everyday accepted observed phenomema(Flemings RHR and Lenz etc) What are the electrical conductivity properties of the both the solid and liquid cores at such high temperatures and pressures? This is something no model appears able to answer . However one thing can be certain. The liquid core must have conductive properties otherwise the magnetic field and its associated properties would not be observed. Its an interesting question though and could probably be answered speculatively by calculating backwards if one had all the data. First measure the strength of the magnetic field at any point on the earths surface and calculate what electrical current at any radius distance from the center in the liquid core would be neccesary to produce such an observed field strength Are there significant differences in the electrical properties of the two types of core and intermediates? This is hard to answer not having been there and measured in situ but.. I would hypothesise that the solid core would not display a noticeable electrical current considering that it is the rotation and the mechanical `shear` across the liquid core.(Ie: the difference in rotational speeds of the outer and inner liquid core) that I suggest induces the electrical current. Having said that it is implicit in my model that a heated liquid metal can carry an electrical curent. If it couldnt then when it is rotated it couldnt allow a dynamo effect to occur and be observed. Neither in the earths core nor in experiments like... *...Generation of a Magnetic Field by Dynamo Action in a Turbulent Flow of Liquid Sodium. R. Monchaux et al 2007 So yes there are and these differences are directly a result of the mechanical difference between a solid and a rotating liquid conductor. Ive explained this elsewhere by suggesting that a electric current is not a transfer or stream of electrons but rather a mechanical rotation of one atoms magnetic field by another. In fact the Faraday wheel can be explained better using this mechanical model then any electron stream model can explain. What are the electircal properties of the junctions between the liquid metal core and the semisolid magma mantle? Is magma at such high temperatures and pressures still going to be an insulator? *What about magma with a high level of liquid metal embedded in it possibly as a metal droplet ('aerosol'?) or as metal complexes with partially dissolved magma impurities. Im not familar with the constituents of surface` magma` so I can only speculate on its properties. Im assuming for now that the magma is the liquid core that has penetrated and cooled partially in the mantle to a more lumpy granular consistency. If the magma is currently observed to be an insulator then that must be because its not allowed to rotate or shear due to its constricted circumstances and... It must also be cooler and partially solidified . More crystaline maybe then the liquid core. This would inhibit the shear effect between freer moving atoms in the liquid core that produces the dynamo I describe. Is magma going to be be withdrawing electric charge from the liquid metal core, or adding charge to it? *Are the electrical junctions at the magma-core boundary significant when it comes to the earth's magnetic field? *What would be the likely electrical and magnetic properties of magma particles flowing and being carried by the physical movement of the liquid metal in the outer liquid metal core? *Is the magma-core boundary significant when it comes to geomagnetism? If the magma isnt rotating then it seems likely to me that it must act as an insulator. I m not that familar with the differences between magma and liquid core, but I imagine it has a more granular consistency then the liquid core which in turn would inhibit the shear between atoms in the liquid core that then results in the dynamo effect during rotation. On a non-electrical side note, is the more solid inner metal core generally plastic? Would it allow the migration of heavier metal components further toward the center. (Effectively concentrating lead, uranium, and the heavier metals toward the furthest and lowest interior?) Interesting question. I suggested in the initial post that the solid core must have elastic properties but that it could be elastic in the sense that it is like larged lumped collection rather than an `elastic` solid. I believe that papers like .. Andrew Jephcoat and Keith Refson (2001-09-06). "Earth science: Core beliefs". Nature 413: 27-30. doi:10.1038/35092650....suggest similar properties. So if its solid but elastic then presumably heavier elements would migrate through the liquid core to attach to and `grow` the solid core. *Its hard to say if this solid would allow elements to migrate through to the center. Maybe a way to test this would be to heat a metal alloy lump to a point where its soft but not liquid and then spin it to see if any of the elements migrate within the spinning lump.

Basic questions: As far as I see almost all theoretical models, not just mine, can only speculate on how exactly the field is induced and what properties or constituents the liquid and solid cores have. In fact all the theoretical models Ive read cannot even explain how the field seeds itself. They resort to an imaginary unexplained spontaneous appearance of a seed field. Thats part of the reason why I posted my model here. I can explain how the field is generated and sustained by using everyday accepted observed phenomema(Flemings RHR and Lenz etc) What are the electrical conductivity properties of the both the solid and liquid cores at such high temperatures and pressures? This is something no model appears able to answer . However one thing can be certain. The liquid core must have conductive properties otherwise the magnetic field and its associated properties would not be observed. Its an interesting question though and could probably be answered speculatively by calculating backwards if one had all the data. First measure the strength of the magnetic field at any point on the earths surface and calculate what electrical current at any radius distance from the center in the liquid core would be neccesary to produce such an observed field strength Are there significant differences in the electrical properties of the two types of core and intermediates? This is hard to answer not having been there and measured in situ but.. I would hypothesise that the solid core would not display a noticeable electrical current considering that it is the rotation and the mechanical `shear` across the liquid core.(Ie: the difference in rotational speeds of the outer and inner liquid core) that I suggest induces the electrical current. Having said that it is implicit in my model that a heated liquid metal can carry an electrical curent. If it couldnt then when it is rotated it couldnt allow a dynamo effect to occur and be observed. Neither in the earths core nor in experiments like... *...Generation of a Magnetic Field by Dynamo Action in a Turbulent Flow of Liquid Sodium. R. Monchaux et al 2007 So yes there are and these differences are directly a result of the mechanical difference between a solid and a rotating liquid conductor. Ive explained this elsewhere by suggesting that a electric current is not a transfer or stream of electrons but rather a mechanical rotation of one atoms magnetic field by another. In fact the Faraday wheel can be explained better using this mechanical model then any electron stream model can explain. What are the electircal properties of the junctions between the liquid metal core and the semisolid magma mantle? Is magma at such high temperatures and pressures still going to be an insulator? *What about magma with a high level of liquid metal embedded in it possibly as a metal droplet ('aerosol'?) or as metal complexes with partially dissolved magma impurities. Im not familar with the constituents of surface` magma` so I can only speculate on its properties. Im assuming for now that the magma is the liquid core that has penetrated and cooled partially in the mantle to a more lumpy granular consistency. If the magma is currently observed to be an insulator then that must be because its not allowed to rotate or shear due to its constricted circumstances and... It must also be cooler and partially solidified . More crystaline maybe then the liquid core. This would inhibit the shear effect between freer moving atoms in the liquid core that produces the dynamo I describe. Is magma going to be be withdrawing electric charge from the liquid metal core, or adding charge to it? *Are the electrical junctions at the magma-core boundary significant when it comes to the earth's magnetic field? *What would be the likely electrical and magnetic properties of magma particles flowing and being carried by the physical movement of the liquid metal in the outer liquid metal core? *Is the magma-core boundary significant when it comes to geomagnetism? If the magma isnt rotating then it seems likely to me that it must act as an insulator. I m not that familar with the differences between magma and liquid core, but I imagine it has a more granular consistency then the liquid core which in turn would inhibit the shear between atoms in the liquid core that then results in the dynamo effect during rotation. On a non-electrical side note, is the more solid inner metal core generally plastic? Would it allow the migration of heavier metal components further toward the center. (Effectively concentrating lead, uranium, and the heavier metals toward the furthest and lowest interior?) Interesting question. I suggested in the initial post that the solid core must have elastic properties but that it could be elastic in the sense that it is like larged lumped collection rather than an `elastic` solid. I believe that papers like .. Andrew Jephcoat and Keith Refson (2001-09-06). "Earth science: Core beliefs". Nature 413: 27-30. doi:10.1038/35092650....suggest similar properties. So if its solid but elastic then presumably heavier elements would migrate through the liquid core to attach to and `grow` the solid core. *Its hard to say if this solid would allow elements to migrate through to the center. Maybe a way to test this would be to heat a metal alloy lump to a point where its soft but not liquid and then spin it to see if any of the elements migrate within the spinning lump. However if the solid core is a collection of seperate fused smaller core pieces then I think that like clothes in a washing machine they would churn and heavy elements would be drawn in to solidify on a solid piece of the core, churn and then maybe be ejected or recycled over time back into the hotter liquid core again. In this case a equilibrium would be better maintained and the heavy metal balance between solid and liquid core maintained.

Seanwww.gammarayburst.com- Hide quoted text - - Show quoted text - metallic bonding means the outer electrons are shared by all the nuclei in that material. you need a mechanism to induce current flow and i tell you that electrons are free to move in the core. the dynamo mechanism maintains the field ,by the action of fluid motion, on the field lines ,in an electrically conducting fluid. what's needed is some way to start the initial field. the consensus is that the early solar nebula contained its own field in the particles that formed the sun . this is the field that initiated the earths field as it formed. note: that bodies lacking a metallic core or with a core contaminated with non siderophiles will either never form a dynamo mechanism or will be catastrophically unstable. please see The Origin of the Solar System edited by S.

Thats the main point my | | model was stating and it still stands. | | And rather than parralel, as Ive suggested previously, | | the liquid core induces a current at right angles to | | its motion.

I think Ill have to | | change my simulation at.. | |http://www.youtube.com/watch?v=CiCBrXKIH_0 | | To one that has the current direction from core to mantle | | rather than rotating around the core. | | Nonettheless when the direction of the motion reverses the | | inducedfieldstill reverses. This is whats observed and means | | my model is still consistent with the observations and with | | Lenz and Fleming. | | I think essentially this is similar to what | | happens in the faraday wheel? Thefieldis at right angles | | to the current and motion. And the motion is at right | | angles to thefieldand current. | | Whatearthscore shows us and what...R. Monchaux et al | | (Generation of aMagneticFieldby Dynamo Action in a | | Turbulent Flow of Liquid Sodium 2007)... | | confirm is that where a liquid faraday wheel rotates ..the shear | | of the atoms motion across the radius of the rotating liquid | | supplies the induced current which in turn induces themagnetic | |field.

That should be "you're", a contraction of "you are". You're a prat, your English is atrocious. **** off. *plonk* As far as I aware using `****` with `off` is also an example of what one might call `atrocious` English But just for sake of argument lets say your claim is correct that the fridge magnet atoms are not the source of the magnetism coming from the fridge magnet. You still have yet to answer a few questions and supply some substantiation rather than slinging a few insults. What other medium or material that isnt made of atoms does account for the observed magnetic field? What binds this imaginary force you invoke to the atoms in your fridge magnet And why is it that when you move your fridge magnet , does the magnetic field seem to move with it? Your model needs a lot of explaining. Personally I think Ill stick with the concept that atoms are the source of magnetism and that each atom is in analogy a bar magnet with n-s polarity. Anyways you still have yet to explain why you mistakenly thought that the earths core wasnt moving relative to the mantle.
