Question
There are four light - weight - rod samples A, B, C, D separately suspended by threads. A bar magnet is slowly brought brought near each sample and the following observation 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
(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
Options
A.B is of a paramagnetic material
B.C is of a diamagnetic material
C.D is of a ferromagnetic material
D.A is of a non-magnetic material
Solution
Diamagnetic will be feebly repelled
Paramagnetic will be feebly attracted
Ferromagnetic will be strongly attracted
Therefore A is of diamagnetic material. B is of the paramagnetic material. C is of ferromagnetic material. D is non magnetic material.
Paramagnetic will be feebly attracted
Ferromagnetic will be strongly attracted
Therefore A is of diamagnetic material. B is of the paramagnetic material. C is of ferromagnetic material. D is non magnetic material.
