Why should the permeability of a paramagnetic material be expected to decrease with increasing temperature?

Short Answer

Expert verified

The randomization of atomic magnetic moment due to increase thermal agitation leading to decrease in the permeability of the paramagnetic material.

Step by step solution

01

Definition of paramagnetic material

The term paramagnetic material may be defined as the material when placed in magnetic field they get weakly magnetized in the direction of magnetizing field.

02

Explain the permeability of a paramagnetic material be expected to decrease with increasing temperature

For a paramagnetic material the atomic magnetic moment aligned themselves parallel to the external magnetic field which opposed by random thermal motion, for this reason the paramagnetic material be expected to decrease with increasing temperature.

Hence,the randomization of atomic magnetic moment due to increase thermal agitation leading to decrease in the permeability of the paramagnetic material.
