Magnetic moment of n unpaired electrons is given by $\mu\sqrt{\text{n(n-2)}}$B.M.
Explanation:
Diamasnetic substances are repelled by an applied magnetic field.[since,it has no unpaired electrons]
Paramagnetic substances,due to presence of unpaired free electrons in them,are attracted by an applied magnetic field.
Magnetic moment of nunpaired electrons is given by the formula,magnetic moment $\mu\sqrt{\text{n(n+2)}}.$
