In physics, mainly quantum mechanics and particle physics, a spin magnetic moment is the magnetic moment caused by the spin of elementary particles.
For example, the electron is an elementary spin-1/2 fermion.
Quantum electrodynamics gives the most accurate prediction of the anomalous magnetic moment of the electron.
Magnetic moment, also known as magnetic dipole moment, is the measure of the object's tendency to align with a magnetic field. “Magnetic Moment is defined as magnetic strength and orientation of a magnet or other object that produces a magnetic field.” The magnetic moment is a vector quantity.
