At the centre of a long solenoid carrying a current of , the magnetic intensity is measured to be . A rod is inserted as the core in the solenoid, and the magnetization of the core is found to be . Identify whether the material of the rod is paramagnetic, diamagnetic, or ferromagnetic.
Options
- AFerromagnetic
- BAntiferromagnetic
- CParamagnetic
- DDiamagnetic
Correct answer
C. Paramagnetic
Step-by-step solution
The magnetic susceptibility of a material is defined as the ratio of its magnetization to the magnetic intensity .
Substituting the given values:
Since the magnetic susceptibility is a small positive value, the material of the rod is paramagnetic.
Substituting the given values:
Since the magnetic susceptibility is a small positive value, the material of the rod is paramagnetic.
