Question

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 1

S. No.			Ferromagnetic
(i)	Intensity of magnetisation	Negative and very small	Positive and very large
(i)	Behaviour in nonuniform magnetic field	Attracted towards a region of weaker magnetic field	Attracted towards a region of stronger magnetic field.
(iii)	Susceptibility	Negative and small 0<χ<∈E small quantity.	Positive and large χ of the order of hundreds & thousands.
