Distinguish between diamagnetic and ferromagnetic materials in respect of their (i) intensity of magnetisation (ii) behaviour in non-uniform magnetic field and (iii) susceptibility.

Answer»
S. No.S. No.S. No. Ferromagnetic
(i)Intensity of magnetisationNegative and very small Positive and very large
(ii)Behaviour in nonuniform magnetic fieldAttracted towards a region of weaker magnetic field Attracted towards a region of stronger magnetic field.
(iii)SusceptibilityNegative and small 0<χ<∈∈ small quantity. Positive and large χ of the order of hundreds & thousands.
