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:
- (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 $|\chi|=10^{2}$.
