Answer 1

The magnetic susceptibility of ferromagnetic material in paramagnetic region is given by Curie-Weiss Law, which is presented as:
$χ = \frac{C}{T - T _{C}}$
where $T_{C}$ is the critical temperature and $χ$ is magnetic susceptibility at temperature $T$ .
Thus $χ$ Vs $T$ graph is a hyperbola.
Hence the correct representation of the curve is the option B.

Answer 2

The magnetic susceptibility of ferromagnetic material in paramagnetic region is given by Curie-Weiss Law, which is presented as:

χ = \frac{C}{T - T _{C}}

where

T_{C}

is the critical temperature and

χ

is magnetic susceptibility at temperature

T

.

Thus

χ

Vs

T

graph is a hyperbola.

Hence the correct representation of the curve is the option B.
