Magnetic moment - Wikipedia
The magnetic field of any magnet can be modeled by a series of terms for which each term is more complicated (having finer angular detail) than the one before it. The first three terms of that series are called the monopole (represented by an isolated magnetic north or south pole) the dipole (represented by two equal and opposite magnetic poles), and the quadrupole (represented by four poles that t

Magnetism on the Atomic Level - Boston University
A current loop has a magnetic moment μ, so for the orbiting electron we get: μ = IA = (ev/2πr) * (πr2) = evr/2 If we multiply top and bottom by m, the electron mass, we get mvr in the numerator. Therefore, by the Bohr model, μ = eL/2m. The orbital magnetic moment of the electron is proportional to its orbital angular momentum.
