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 $(C)$.

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