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.comhttp://www.youtube.com/profile?user=jaymoseleygrb it is chemical bonds , not gravity that determines the chemical nature of the core . the core is composed of siderophiles. that is, the elements of the core bond via metallic bonds . this is further supported by density calculations that indicate a likely Fe/Ni composition. the massive elements , including the radioactive elements are oxyphiles and readily bond to O via ionic bonding. due to this they occur only in the mantle and crust . in fact the mantle can be considered as a sea of O with the rest of the elements as little more than minor pollutants .
