Given below are two statements:

Statement I : The diamagnetic property depends on temperature.

Statement II : The induced magnetic dipole moment in a diamagnetic sample is always opposite to the magnetising field.

In the light of given statements, choose the correct answer from the options given below

  1. Both Statement I and Statement II are False
  2. Statement I is incorrect but Statement II is true
  3. Statement I is correct but Statement II is false
  4. Both Statement I and Statement II are true

Solution

The properties of a diamagnetic material are as follows:

1. The susceptibility has a low negative value.

2. Susceptibility is independent of temperature.

3. The relative permeability is slightly less than one.

4. When placed in a non-uniform magnetic field they have a tendency to move away from the field.

5. When suspended freely in a uniform magnetic field, they set themselves perpendicular to the direction of the magnetic field.

Hence, Statement I is false, but statement II is true.
