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.
