(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
