Question 38 of 57
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
Show answer and solution
Answer: (B) Statement I is incorrect but Statement II is true
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.
