Question

What is curie Weiss's law?

Answer 1

The Curie-Weiss law:

The Curie-Weiss law is an essential statement throughout electromagnetism that states that perhaps the magnetic susceptibility of a ferromagnet throughout the paramagnetic region is considerably greater than its Curie temperature point.

1. The magnetic polarization, as well as the magnetization of such a magnetic material, expresses the density of induced but rather permanent magnetic moments throughout the vector field.
2. The magnetic moment can develop as a result of a small electric current generated by electron spin, the electron mobility in an atom, or the nucleus spin.

Mathematical representation:

Mathematically, Curie-Weiss law can be represented as:

$\mathrm{X}=\frac{\mathrm{C}}{\mathrm{T}-{\mathrm{T}}_{\mathrm{c}}}$

Here,

C is material specific Curie.

T is the absolute temperature.

T_c is curie temperature

Therefore, there is a transition temperature at which ferromagnetic materials exhibit paramagnetic behavior.
