Hi RL Seems to me that the Earth's core could be liquid iron,and
around this inner core is a solid iron other core shell. Spinning motion
would create a dynamo either way. RL I have never heard how magnetisim
overcomes this great high temperature. Madam Curie,and her husband
proved heat kills magnetisim. Its called the "Curie effect". Have we
ever tried to build a liquid iron dynamo in a lab? Heat a bar magnet hot
enough and it losses all its magnetic force.. I think lots of
fudging goes into our Earth core theories,and too few experiments. Our
theory that Jupiter has a solid hydrogen core was kind of far out
thinking,and yet we created solid stable hydrogen in a Tennessee lab(I
liked that) One could easily come up with fission creating an
electric current,and that gives the flow of electrons going from the
south pole to the north pole. This theory has some merit. Bert
