Magnetic moment$\left(\mathrm{\mu }\right)=\sqrt{\mathrm{n}\left(\mathrm{n}+2\right)}$
More than value of n, more will be magnetic moment.
$\mathrm{T}{\mathrm{i}}^{+2}$electronic configuration;
$3{\mathrm{d}}^2\mathrm{ }$$\mathrm{\mu }=\sqrt{2\left(2+2\right)}=2.82$
${\text{Ti}}^{+3}\Rightarrow 3{\mathrm{d}}^1$$\mathrm{\mu }=\sqrt{1\left(1+2\right)}=\sqrt{3}=1.73$
${\mathrm{V}}^{+2}\Rightarrow 3{\mathrm{d}}^3$$\mathrm{\mu }=\sqrt{3\left(3+2\right)}=3.87$
$\mathrm{S}{\mathrm{c}}^{3+}\Rightarrow \left[\mathrm{A}\mathrm{r}\right]$no unpaired electron.$\to \mathrm{\mu }=0$
Hence Order of Magnetic Moment is$\mathrm{ }{\mathrm{V}}^{+2}>\mathrm{T}{\mathrm{i}}^{+2}>\mathrm{T}{\mathrm{i}}^{+3}>\mathrm{S}{\mathrm{c}}^{+3}$
