# What is curie weiss law?

The Curie-Weiss law is one of the important laws in electromagnetism that says that the magnetic susceptibility is grater than the Curie temperature point of a ferromagnet in the paramagnetic zone. A magnet’s magnetic moment is a property that defines its torque in the presence of an external magnetic field.

The density of induced or permanent magnetic moments in the vector field is expressed by the magnetic polarisation or magnetization of a magnetic material. The magnetic moment can form as a result of the microscopic electric current produced by the spin of electrons, electron motion in an atom, or nuclei spin.

$$X = \frac{C}{T-T_{c}}$$

Here,

C = Material specific Curie

T = Absolute temperature

Tc = Curie temperature
