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

C is diamagnetic material

B

D is of a ferromagnetic material

C

A is of a non-magnetic material

D

B is of paramagnetic material

Text Solution

Verified by Experts

The correct Answer is:
D
Paramagnetic material will be feebly attracted, dimagnetic material will be feedbly repelled and ferromagnetic material will be strongly attracted.
