Magnetic susceptibility is a dimensionless proportionality constant that indicates the degree of magnetization of a material in response to an applied magnetic field.
And the relation between Magnetic susceptibility and Temperature can be given as
\(\chi = \frac{C}{{T - {T_c}}}\)
Curie’s constant = C
Magnetic susceptibility = χ
Curie temperature = Tc
The temperature at any given instance = T
Explanation:
Effect of Temperature Ferromagnetism:
The magnetic susceptibility decreases with an increase in temperature.
So, the ferromagnetism decreases with rising temperature.
It is maximum at absolute zero temperature and becomes zero at Curie temperature.
Above this temperature, the ferromagnetic material behaves as a paramagnetic substance.
And hence susceptibility can be given as, \(\chi = \frac{C}{{T - {T_c}}}\) but in this case (T>TC)Last updated on Jun 13, 2025
