Curie's law
In a paramagnetic material the magnetization is related to applied magnetic field as
where
- M is the resulting magnetisation
- B is the magnetic flux density of the applied field, measured in teslas
- T is absolute temperature, measured in kelvins
- C is a material-specific Curie constant
This relation is called Curie's law after the great physisist Pierre Curie. In words it says that the magnetisation and hence the susceptibility will decrease when the temperature increases.
Curie's law can be seen as a simplification of the more general Curie-Weiss law.
