Magnets are not reliant on the Earth's magnetic field. They work because of the Electromagnetic Force, one of the four fundamental forces of nature. Perhaps you actually are talking about compasses?
It proves nothing of the sort.because the field radiates in all directions equally from a fixed point.Care to elaborate on that.
according to people who think the earth is round, the center of the field is the earth's core radiates in all directions, so the fact that compasses work everywhere and point to north and south regions, proves to them the earth is a sphere.

How? the waves produced from it go into 3 spacial dimensions.
The model for the Earth's magnetic field is based on a round earth, metallic core etc., but that in itself doesn't mean the Earth has to be round. But what a FE'r does need to do is explain how the magnetic field works on a flat Earth.
That I would really love to see.
