What is curie Weiss's law?
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.
Mathematically, Curie-Weiss law can be represented as:
C is material specific Curie.
T is the absolute temperature.
Tc is curie temperature
Therefore, there is a transition temperature at which ferromagnetic materials exhibit paramagnetic behavior.
