Question
Distinguish between diamagnetic and ferromagnetic materials in terms of
i. susceptibility and
ii. their behaviour in a non-uniform magnetic field
✓

Answer

i. Susceptibility for diamagnetic material:
It is independent of magnetic field and temperature (except for bismuth at low temperature).
Susceptibility for ferromagnetic material:
ii. Behaviour in non-uniform magnetic field:
Diamagnetic substances are feebly repelled, whereas ferromagnets are strongly attracted by non-uniform field.
