NEET Physics Magnetic Properties of Materials MCQ Question

Type: MCQ-numerical-Medium-Class 12

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

A

1.0001

B

1.001

C

1.01

D

1.1

Correct Answer

Option A

Detailed Explanation

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