A model for quantized motion of an electron in a uniform magnetic field $\displaystyle B$ states that the flux passing through the orbit of the electron is $\displaystyle n(h / e)$ where $\displaystyle n$ is an integer, $\displaystyle h$ is Planck's constant and $\displaystyle e$ is the magnitude of electron's charge. According to the model, the magnetic moment of an electron in its lowest energy state will be ( $\displaystyle m$ is the mass of the electron)
