Magnetic Materials & Curie Law

Relative permittivity and permeability of a material $\varepsilon_r$ and $\mu_r,$ respectively. Which of the following values of these quantities are allowed for a diamagnetic material?

Show answer and solution

Answer: (b)

Diamagnetic: $\chi < 0$ , so $\mu_r < 1$ .
For any material medium $\varepsilon_r > 1$ (vacuum has 1).
Only $\varepsilon_r = 1.5$ , $\mu_r = 0.5$ satisfies both.
So the answer is (b).
