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

Options

  1. Aεr=0.5,μr=1.5\varepsilon_{\mathrm{r}}=0.5, \mu_{\mathrm{r}}=1.5
  2. Bεr=1.5,μr=0.5\varepsilon_{\mathrm{r}}=1.5, \mu_{\mathrm{r}}=0.5
  3. Cεr=0.5,μr=0.5\varepsilon_r=0.5, \mu_r=0.5
  4. Dεr=1.5,μr=1.5\varepsilon_{\mathrm{r}}=1.5, \mu_{\mathrm{r}}=1.5

Correct answer

B. εr=1.5,μr=0.5\varepsilon_{\mathrm{r}}=1.5, \mu_{\mathrm{r}}=0.5
