Magnetism and Matter - Result Question 12

16. The magnetic susceptibility is negative for :

(a) diamagnetic material only

(b) paramagnetic material only

[2016]

(c) ferromagnetic material only

(d) paramagnetic and ferromagnetic materials

Show Answer

Answer:

Correct Answer: 16. (a)

Solution:

  1. (a) Magnetic susceptibility $\chi$ for dia-magnetic materials only is negative and low $|\chi|=-1$; for paramagnetic substances low but positive $|\chi|=1$ and for ferromagnetic substances positive and high $|\chi|=10^{2}$.
