Vedclass · Answer

(C) Magnetic susceptibility $\chi$ is a dimensionless quantity that indicates the degree of magnetization of a material in response to an applied magnetic field.For diamagnetic materials, $\chi$ is small and negative.For paramagnetic materials, $\chi$ is small and positive.For ferromagnetic materials, $\chi$ is large and positive.Given that the susceptibility is $ 400 $, which is a large positive value, the material belongs to the class of ferromagnetic materials.

List-$I$ (Material)	List-$II$ (Susceptibility $(\chi)$)
$A$. Diamagnetic	$I$. $\chi=0$
$B$. Ferromagnetic	$II$. $0 > \chi \geq -1$
$C$. Paramagnetic	$III$. $\chi >> 1$
$D$. Non-magnetic	$IV$. $0 < \chi < \varepsilon$ (a small positive number)

$A$ susceptibility of a certain magnetic material is $ 400 $. What is the class of the magnetic material $ ? $
