Question:
Which one of the following characteristics is not associated with a paramagnetic material?
Which one of the following characteristics is not associated with a paramagnetic material?
Show Hint
For paramagnets:
\[
\chi \propto \frac{1}{T}
\]
So susceptibility decreases when temperature increases.

- It is weakly magnetised in the direction of the magnetising field, in which it is placed
- Its magnetic permeability is greater than one
- Its magnetic susceptibility is positive
- Its magnetic susceptibility increases with rise in temperature
- Its individual atom/molecule/ion has a net non-zero magnetic moment of its own
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
For a paramagnetic substance:
- susceptibility is positive,
- permeability is slightly greater than 1,
- individual atoms or ions have non-zero magnetic moments.
Also, paramagnetic susceptibility decreases with rise in temperature according to Curie's law:
\[
\chi \propto \frac{1}{T}
\]
So statement (D) is not associated with paramagnetic materials.
Hence,
\[
\boxed{(D)}
\]
