Show Answer
Solution:
Ans. Depiction of behaviour :
(i) Diamagnetic
Paramagnetic
(ii) Their justification
(i)
(ii)
The Field lines are repelled or expelled and the field inside the material is reduced.
In the presence of magnetic field, the individual atomic dipoles can get aligned in the direction of the applied magnetic field. Therefore, field lines get concentrated inside the material and the field inside is enhanced.
