Scientists found Alternating bands of magnetism.
They discovered sea floor spreading.
No, they are silly.
reversed itself in the past. hth :)
Magnetic bands for balance
Van Allen Belt
They indicate that the Earth's magnetic field has undergone shifting of the positions of it's poles several times in the past.
