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

Obtain an expression for the orbital magnetic moment of an electron rotating about the nucleus in an atom and explain the gyromagnetic ratio.

An electron of charge $e$ and mass $m$ is moving in a circular path of radius $r$ with a uniform angular speed $\omega$. Which of the following statements are correct?

Bohr magneton is given by (symbols have their usual meanings)

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

Explain orbital magnetic moment and spin magnetic moment.
