Question

Which one of the following characteristics is not associated with a paramagnetic material?

• A. It is weakly magnetised in the direction of the magnetising field, in which it is placed
• B. Its magnetic permeability is greater than one
• C. Its magnetic susceptibility is positive
• D. Its magnetic susceptibility increases with rise in temperature
• E. Its individual atom/molecule/ion has a net non-zero magnetic moment of its own

Hint:

For paramagnets: \[ \chi \propto \frac{1}{T} \] So susceptibility decreases when temperature increases.

Answer 1

The Correct Option is D
