Question:
Could a hollow ball be magnetized so one pole is on the inside surface of the ball and the other pole is on the outer surface?


Replies:
No, because the field required to magnetize the ball cannot exist. However, such a magnetized ball can be constructed from pieces separately magnetized. Somewhere there must be flux leakage, because field lines cannot simply end in the middle of the ball.
