Relative permittivity and permeability of a material are $\varepsilon_{\mathrm{r}}$ and $\mu_{\mathrm{r}}$, respectively. Which of the following values of these quantities are allowed for a diamagnetic material?

• A

  $\varepsilon_{\mathrm{r}}=0.5, \mu_{\mathrm{r}}=1.5$
• Correct answer
  B

  $\varepsilon_{\mathrm{r}}=1.5, \mu_{\mathrm{r}}=0.5$
• C

  $\varepsilon_r=0.5, \mu_r=0.5$
• D

  $\varepsilon_{\mathrm{r}}=1.5, \mu_{\mathrm{r}}=1.5$

Hence, the correct answer is option: 'B'.
