Relative permeability of paramagnetic material is greater then ‘1’
Permeability is the ability of a material to support the formation of a magnetic field within itself.
$\mathit{\mu }=\frac{\mathit{B}}{\mathit{H}}\left(\frac{\mathit{H}}{\mathit{M}}\right)$
$\mathit{\mu }={\mathit{\mu }}_0\mathrm{}{\mathit{\mu }}_{\mathit{r}}$
${\mathit{\mu }}_{\mathit{r}}$ = relative permeability
${\mathit{\mu }}_{\mathit{o}}$ = permeability of vacuum
