Explain Curie temperature. |
|
Answer» Solution :The ferromagnetic property DEPENDS on temperature. Increasing the temperature of ferromagnetic substance, dipole moment of its molecules become random and DESTROYED. At high enough temperature a ferromagnetic substance BECOMES PARAMAGNETIC. The temperature of transition from ferromagnetic to paramagnetism is called the Curie temperature `(T_C)`. Curie temperature that is in the paramagnetic phase is described by `CHI = (C )/( T- T_C) (T gt T_C)` The Curie temperature `(T_C)` of some of the ferromagnetic material :
