The product of magnetic susceptibility ( χ) and absolute temperature (T) is constant for a (a) diamagnetic substance. (b) paramagnetic substance. (c) ferromagnetic substance. (d) paramagnetic as well as ferromagnetic substance.

Answer: (b). Curie law: χ = C/T ⇒ χ T = C (constant). It holds for paramagnetic substances (ferromagnets follow χ = (C)/(T - TC) only above TC). So the answer is (b) paramagnetic substance.

Magnetic Materials & Curie Law

The product of magnetic susceptibility ( $\chi$ ) and absolute temperature (T) is constant for a

Show answer and solution

Answer: (b)

Curie law: $\chi = \dfrac{C}{T} \Rightarrow \chi T = C$ (constant).
It holds for paramagnetic substances (ferromagnets follow $\chi = \dfrac{C}{T - T_C}$ only above $T_C$ ).
So the answer is (b) paramagnetic substance.
