Magnetic moment

product of the electric current through a loop, the area enclosed by the loop and the unit vector perpendicular to the loop

unit of magnetic moment (approx. 9.2 J/T); the magnetic dipole moment of an electron orbiting an atom with angular momentum ℏ in the Bohr model

quantum field-theoretic differences of magnetic properties than expected from classical theories

intrinsic magnetic dipole moment of neutrons

spin of an electron

magnetic moment of an atomic nucleus
