The angle made by the orbital angular momentum of an electron with the direction of its orbital magnetic moment is: (in $^{\circ}$)

$A$ particle of charge '$q$' and mass '$m$' moves in a circular orbit of radius '$r$' with angular speed '$\omega$'. The ratio of the magnitude of its magnetic moment to that of its angular momentum depends on

The ratio of angular momentum $\overrightarrow{L}$ of an electron to the magnetic dipole moment $\overrightarrow{m}_{\text{orb}}$ is (where $m$ is the mass of the electron and $e$ is the charge on the electron).

The magnetic moment $(\mu)$ of a revolving electron around the nucleus varies with principal quantum number $n$ as

In the Bohr model,an electron moves in a circular orbit around the proton. Considering the orbiting electron to be a circular current loop,the magnetic moment of the hydrogen atom when the electron is in the $n^{th}$ orbit is:

The magnetic moment of a revolving electron of charge $e$ and mass $m$ in terms of the angular momentum $L$ of the electron is:
