Vedclass · Answer

(C) Ferromagnetic and ferrimagnetic substances possess ordered magnetic domains at room temperature.On heating,the thermal energy increases,which leads to the randomisation of the magnetic moments (spins).This randomisation results in the loss of the ordered magnetic structure,causing the substance to become paramagnetic.The reason provided is incorrect because the electrons do not change their intrinsic spin; rather,the alignment of the spins becomes random due to thermal agitation.

Assertion : On heating ferromagnetic or ferrimagnetic substances,they become paramagnetic.
Reason : The electrons change their spin on heating.
