Don't know about magnetics, but thermodynamics/geothermics doesn't seem to be your strong suit.
Seen it first hand how you can drill/dig a mile deep and it'll be some 40 deg C or more warmer down there. Anyone into drilling or mining (e.g. oil & gas) knows about that too.
Don't know what theory you have about Earth's magnetic field, but it's more than likely not cold in there.
Ever heard about shear waves and compressional waves?
Would be curious, if it's "cold in there", how you'd explain observations in (pic).
It's mechanical waves, frendo, like sound.
Nothing electromagnetic involved in that idea or the pic I posted.
Also, the term "shear waves" doesn't exist in the EM realm, but both concepts (P- & S-wave) exist in seismics/seismology.
So there you go ….. I might like your idea (that I don't know about) re Earth's magnetic field, but it's most likely not "cold in there".
