Which of the following combination will be represented by a diamagnetic material?
Which of the following combination will be represented by a diamagnetic material?
(a), (c)
(a), (d)
(b), (d)
(b), (c)
Explanation
For diamagnetic material
$$\chi $$ is independent of temperature and negative.
Magnetisation (M) is directly proportional to H (The relation between magnetisation and magnetising field, M = –mH)
