प्रश्न
In what way is the behaviour of a diamagnetic material different from that of a paramagnetic, when kept in an external magnetic field?

उत्तर
When a bar of diamagnetic material is placed in an external magnetic field, the field lines are repelled or expelled and the field inside the material is reduced.
Whereas when a paramagnetic material is placed in an external magnetic field, the field lines are attracted towards it. Thus the field lines get concentrated inside the material and the field inside is enhanced.
