The gyromagnetic ratio of an electron is equal to . . . . . . times the specific charge of an electron.

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).

Define Bohr magneton using Bohr's first hypothesis.

$A$ 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 is

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

An electron is moving in an orbit around the nucleus in an atom. Let $m$ be the orbital magnetic moment and $L$ be the angular momentum of the electron,then
