Vedclass · Answer

(C) The magnetic moment $(M)$ of a ferromagnetic material decreases as the temperature $(T)$ increases due to the increased thermal agitation of the atomic dipoles.As the temperature approaches the Curie temperature $(T_c)$,the magnetic moment decreases rapidly and becomes zero at $T = T_c$,where the material transitions from ferromagnetic to paramagnetic.The curve that correctly represents this behavior is a non-linear decrease that reaches zero at the Curie temperature,which corresponds to option $(C)$.

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)

The curve representing the relationship between the magnetic moment $(M)$ and the temperature $(T)$ of a ferromagnetic material is:
