There’s no an accepted cause for the magnetic field of the Earth, other than vague handwaving that molten iron is moving around in a uniform fashion without anything moving it. :’) The constant problem since the plate tectonics revolution of the 1960s (Imho, the so-caled ptr, but anyway) has been, how to then explain magnetic reversals. The answer is, there isn’t an answer. :’D
