When a bar magnet is divided into two pi...

When a bar magnet is divided into two pieces,

A

both the pieces lose magnetism.

B

both the pieces behave like individual magnets.

C

both the poles get separated.

D

one piece behaves like a magnet and the other does not.

Text Solution

Verified by Experts

The correct Answer is:
B
Because after all, at atomic level magnetism is due to tiny current loops which always have two magnetic poles, each. Hence each piece behaves like an individual magnet.
