The relative permeability is represented by ${\mathrm{\mu }}_{\mathrm{r}}$ and the susceptibility is denoted by $\mathrm{\chi }$ for a magnetic substance. Then for a paramagnetic substance

 

 

 

• A

  ${\mathrm{\mu }}_{\mathrm{r}}<1,\mathrm{\chi }<0$

• B

  ${\mathrm{\mu }}_{\mathrm{r}}<1,\mathrm{\chi }>0$

• C

  ${\mathrm{\mu }}_{\mathrm{r}}>1,\mathrm{\chi }<0$

• D

  ${\mathrm{\mu }}_{\mathrm{r}}>1,\mathrm{\chi }>0$
