Q. If a diamagnetic substance is brought near the north or the south pole of a bar magnet, it is :

A

repelled by the north pole and attracted by the south pole

B

attracted by the north pole and repelled by the south pole

C

attracted by both the poles

D

repelled by both the poles

Solution:

A diamagnetic substance is weakly repelled by the both poles of a barmagnet.
When a magnet is brought near a bar magnet it gets magnetized.
The magnetization takesplace in a direction that is opposite to the external field.
When a diamagnet is at a distance from a bar magnet , the magnetic field deviates away from the diamagnet.
