Magnetism and Matter question

2011 · Q126

NEETPhysicsMagnetism and MatterMCQ+4 / −1
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 ?
  1. A
    B is of a paramagnetic material
  2. B
    C is of a diamagnetic material
  3. C
    D is of a ferromagnetic material
  4. D
    A is of a non-magnetic material
View written solutionFree

Correct answer: A

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.
