QAIPMT-2011-Ph-1906: NEET 2011 Physics - Class 12 AIPMT-2011-Ph-1906 Solution: There are four light-weight-rod samples A, B, C, D separately…
There are four light-weight-rod samples 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?
Multiple Choice 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
Step-by-Step Verified 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 paramagnetic material. C is of ferromagnetic material. D is of non-magnetic material.
