There are four light-weight-rod sample A, B, C, D separately suspended by threads. A bar magnet is slowly brought near each sample and the following observations are noted
(i) A is feebly repelled
(ii) B is feebly attracted
(iii) C is strongly attracted
(iv) D remains unaffected
Which one of the following is true?

A

A is of a non-magnetic material

B

B is of a paramagnetic material

C

C is of a diamagnetic material

D

D is of a ferromagnetic material

Text Solution

Verified by Experts

The correct Answer is:
B
diamagnetic material is repelled, para magnetic material is feebly attracted and ferromagnetic material is strongly attracted in the magnetic field.
