Question

Distiguish between paramagnetic and diamagnetic metirials

Answer 1

Paramagnetic materials are attracted by external magnetic fields whereas diamagnetic materials are repelled. Paramagnetic materials have at least one unpaired electron in the system, but diamagnetic materials have all their electrons paired.

Answer 2

1. Paramagnetic materials have at least one unpaired electron in the system, whereas diamagnetic materials have all their electrons paired.

2. Paramagnetic materials are attracted by the external magnetic fields, whereas diamagnetic materials are repelled.

3. The magnetic field created by paramagnetic materials are in the direction of the external magnetic field, whereas the magnetic field created by diamagnetic materials are in the direction opposite to the external magnetic field.

4. Paramagnetism is a stronger magnetic behaviour exhibited only by selective materials, whereas diamagnetism is a weak magnetic behaviour generally shown by all materials and can easily be suppressed in the presence of stronger magnetic properties.

5. Examples of diamagnetic materials are antimony, bismuth,lead,tin, zinc, mercury,gold, phosphorus, whereas aluminium, platinum, oxygen, manganese, chromium are paramagnetic materials.
