Question

Discuss the Curie law for paramagnetic material.

Answer 1

Curie's Law:

In a paramagnetic material, the magnetization of the material is directly proportional to an applied magnetic field. However, if the material is heated, the magnetization is inversely proportional to temperature.

$i.e.M=C\times \left(B/T\right)$

where,

$M$ is the magnetisation

$B$ is the magnetic field, measured in teslas

$T$ is absolute temperature, measured in kelvins

$C$ is a material-specified Curie constant

It was first discovered experimentally by a French physicist, Pierre Curie. it holds for high temperatures or weak magnetic fields.
