Vedclass · Answer

(D) The Curie temperature $(T_c)$ is the temperature above which a ferromagnetic material loses its spontaneous magnetization and undergoes a phase transition to a paramagnetic state.When a ferromagnetic material is heated above its Curie temperature,the thermal agitation of the atoms becomes strong enough to overcome the exchange coupling that aligns the magnetic moments.Consequently,the material loses its ferromagnetic properties and begins to behave like a paramagnetic material.

When a ferromagnetic material is heated to a temperature above its Curie temperature,the material
