NEET Physics Magnetic Properties of Materials MCQ Question with Solution

In a paramagnetic material, if the magnetic susceptibility $\chi$ is 0.0001, what is the relative magnetic permeability $\mu_r$ ?

A

1.0001

B

1.001

C

1.01

D

1.1

Correct Answer

Option A

Detailed Explanation

The relative magnetic permeability $\mu_r$ is related to magnetic susceptibility $\chi$ by the formula $\mu_r = 1 + \chi$ . Substituting $\chi = 0.0001$ , we get $\mu_r = 1.0001$ .
