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
Explanation
[Solution from source] Diamagnetic materials get a weak induced moment opposite to the applied field, so they are pushed towards weaker field regions. This happens regardless of which pole is used, so they are repelled by both poles. Answer (4).
