Current Loop as a Magnetic Dipole

The relation between magnetic moment 'M' of revolving electron and principle quantum number 'n' is

Show answer and solution

Answer: (b)

$\mu = \frac{e}{2m}L$ and by Bohr's rule $L = \frac{nh}{2\pi}$ .
$\mu = \frac{neh}{4\pi m} \propto n$
So the answer is (b) $M \propto n$ .
