The relative permeability is represented by

\mu_{\mathrm{r}}

and the susceptibility by

\chi

for a magnetic substance. Then for a paramagnetic substance.

View answer and explanation

Correct option: B

\mu_{\mathrm{r}}>1, \chi>0

Option B (

\mu_{\mathrm{r}}>1, \chi>0

) is correct because paramagnetic substances have a relative permeability slightly greater than 1 and a positive susceptibility.
