Vedclass · Answer

(B) The Curie temperature $(T_C)$ is a characteristic property of ferromagnetic materials.At temperatures below $T_C$,the material exhibits ferromagnetic properties due to the alignment of magnetic domains.As the temperature increases and reaches $T_C$,the thermal agitation becomes strong enough to overcome the exchange coupling that maintains the alignment of these domains.Consequently,above the Curie temperature,the material loses its spontaneous magnetization and transitions into a paramagnetic state.Therefore,the correct option is $(B)$.

Curie temperature is the temperature above which
