Question

If the north pole of a bar magnet is brought closer to a spherical iron ball then where will be its induced north pole?

• A. 1
• B. 2
• C. 3
• D. There will be no induced magnetic poles as the shape is spherical.

Answer 1

The correct option is A

1

The electromotive force will be induced in the spherical iron ball when the magnet is brought closer to it. Imagine the sphere to be made of many small bar magnets. They will align themselves with their south poles facing the point 2 and hence at position 1, we will get the North Pole.
