Eli5 The earth has a magnetic field, including because of the metal core, but magnets are demagnetized at high temperature. How is this possible

Answer 1

I saw something not too long ago where they were trying to show how the rotating core generated the magnetic field. But they couldn’t make it happen.

So I don’t know if they are certain this is the cause, and this is just an insufficient simulation, or if they just all thought it made sense and kind of accepted it as the best possibility and moved on because they couldn’t test it.
