| Why do you need a question mark at the end of that statement?
| You need the brushes to connect the induced current in the coil
| to the rest of the circuit in a normal setup but..
| The circuit in the liquid core I describe is self contained.
| It doesnt need to be connected *to itself. For instance in a
| dynamo ,.. does the coil that spins in themagneticfieldneed to
| be attached to itself ? No. It only needs brushes if you want
| to attach the rotating coil to an outside circuit. THink of the
|earthsrotating liquid core as a coil that isnt attached to an
| outside circuit. Why do I need brushes? Im not suggesting the
| current in the core needs to be attached to any circuit outside the
| core.If I did ... THEN I would need brushes. But I dont so I
| dont need to specify brushes.
| | The liquid core is connected
| | to itself.
|
| So is the rotor in an AC induction motor, but themagnetic
| fieldreverses 50 times a second (60 in the USA). The Earth's
| magneticfieldis DC.
| Theearthscore is not an ac motor nor does it resemble
| one. Whatever gave you that idea.?
| I certainly never said it resembled an AC induction motor.
| | The current flows around it and doesnt need to be
| | connected to anywhere else by brushes .
|
| The problem with that idea is resistance.
| Is the Earth's core a superconductor?
| No. Otherwise the erathsmagneticfieldwould be tremendously
| powerful. Nonetheless it conducts at least on a residual
| basis. We have the observations of theearthsfieldto
| attest to this. AND,.. the observations that a rotating liquid
| metal will without outside input generate an electromagnetic
|field
| | And you havent made it clear why your diagram proves
| | that Lenzs law is incorrect.

| (wiki)..."The direction of the induced current depends on
| whether the north or south pole of the magnet is
| approaching: an approaching north pole will produce an
| anti-clockwise current (from the perspective of the
| magnet), and south pole approaching the coil will produce
| a clockwise current..."
| Yes I concede this point to you although wiki doesnt mention
| that reversing the motion of the conductor still reverses
| the inducedmagneticfield. 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. From core to mantle. 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. In other words a liquid faraday wheel can induce its own
|fieldas long as force is supplied through rotation,without
| neccesitating an applied externalmagneticfield. I know
| you wont like this but the fact is that this theoretical premise
| I suggest is confirmed by R Monchaux et al. If I was wrong
| then they would not have observed a roating liquid conductor
| generate and sustain amagneticfieldwithout any external
| applied emf.
| | As far as Im aware an electrical
| | current always flows in the direction of the motion of themagnetic
| |field.
|
| I'll change the batteries in my fridge magnets then. My grocery list
| must be about to fall on the floor, I haven't changed them in years.
| Did I ever say that your permanent magnet wasnt permanent?
| No. You imagine facts .I never even mentioned permanent magnets
| or whether or not they are permanent or not.
| | At least thats what my reference indicates. For instance
| | if you have a solenoid arranged so that it is vertical on a
| | desk. If you then move
|
| Move? What's this about "move"?
| I don't move my fridge magnets very much. When I do
| then I create a small current in the door, but no current
| without movement.
| Exactly as I was saying. If you move your magnet,..
| you create a small current.

First you need a magnet to move.

An atom is essentially a magnet.

If you have proof that atoms do not display magnetic properties
including those similar to magnetic poles , please reference this. I
think you imagine it though.
