Question

The variation of magnetic susceptibility ( chi) with absolute temperature T for a ferromagnetic material is (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

Susceptibility of a ferromagnetic substance falls with rise of temperature ( chi=(c/T-Tc)) and the substance becomes paramagnetic above Curie's temperature, so magnetic susceptibility becomes very small above Curie's temperature.

Q. The variation of magnetic susceptibility $(χ)$ with absolute temperature $T$ for a ferromagnetic material is

Susceptibility of a ferromagnetic substance falls with rise of temperature $(χ = \frac{c}{T - T _{c}})$ and the substance becomes paramagnetic above Curie's temperature, so magnetic susceptibility becomes very small above Curie's temperature.

Q. The variation of magnetic susceptibility (χ) with absolute temperature T for a ferromagnetic material is

Susceptibility of a ferromagnetic substance falls with rise of temperature (χ=T−Tc​c​) and the substance becomes paramagnetic above Curie's temperature, so magnetic susceptibility becomes very small above Curie's temperature.
