For ferromagnetic material, the relative permeability (µ_r) , versus magnetic intensity (H) has the following shape

${\mathrm{\mu }}_{\mathrm{r}}=1+\frac{\mathrm{I}}{\mathrm{H}}$

For smaller values of H , value of $\frac{\mathrm{I}}{\mathrm{H}}$ is smaller , but increases slowly with H.

For sufficiently high value of H , as per domain theory, I becomes saturated and ${\mathrm{\mu }}_{\mathrm{r}}$ achieve maximum value.

For higher values of H , I becomes almost constant , so as per  ${\mathrm{\mu }}_{\mathrm{r}}=1+\frac{\mathrm{I}}{\mathrm{H}}$ , we can say ${\mathrm{\mu }}_{\mathrm{r}}$ decreases with H.

Therefore the correct representation of this relation would be
