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
Options
- ABoth Statement I and Statement II are False
- BStatement I is incorrect but Statement II is true
- CStatement I is correct but Statement II is false
- DBoth Statement I and Statement II are true
Correct answer
B. Statement I is incorrect but Statement II is true
Step-by-step 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.
