Type: MCQ-conceptual-Medium-Class 12

The incorrect relation for a diamagnetic material (all the symbols carry their usual meaning and $\varepsilon$ is a small positive number) is:

A

$\mu < \mu_0$

B

$0 \leq \mu_r < 1$

C

$-1 \leq \chi < 0$

D

$1 < \mu_r < 1 + \varepsilon$

Correct Answer

Option D

Detailed Explanation

For diamagnetic materials, the relative permeability $\mu_r$ is less than 1. Option D suggests $\mu_r > 1$ , which is incorrect for diamagnetic materials.
