Vedclass · Answer

(D) The ferromagnetic property of a material is due to the alignment of atomic magnetic moments in the same direction. When the temperature of a ferromagnetic material is increased beyond its Curie temperature $(T_c)$,the thermal agitation becomes strong enough to disrupt the long-range order of the magnetic moments. As a result,the material loses its spontaneous magnetization and transitions into a paramagnetic state. Therefore,nickel will show paramagnetism above its Curie temperature.

Nickel shows ferromagnetic property at room temperature. If the temperature is increased beyond Curie temperature,then it will show:
