In atomic physics, the magnetic dipole moment of an electron is involved in a variety of important atomic processes and effects. Atomic physics (or atom physics) is physics of the electron hull of atoms. ...

Orbital magnetic dipole moment

Generally, for a hydrogen atomic electron in state Ψ_n,l,m where n,l and m are the principal, azimuthal and magnetic quantum numbers respectively, the total magnetic dipole moment due to orbital angular momentum is given by General Name, Symbol, Number Hydrogen, H, 1 Chemical series nonmetals Group, Period, Block 1 (IA), 1, s Density, Hardness 0. ... Properties The electron is a subatomic particle. ... A quantum number is a number used to parametrise certain properties of particles or other systems in quantum mechanics. ... This article is about the electromagnetic phenomenon. ... In physics, angular momentum intuitively measures how much the linear momentum is directed around a certain point called the origin; the moment of momentum. ...

Where μ_B is the Bohr magneton. The Bohr magneton (symbol ) is named after the physicist Niels Bohr. ...

The z-component of the orbital magnetic dipole moment is given by

μ_z = μ_Bm

Spin magnetic dipole moment

The total magnetic dipole moment resulting from the electron's intrinsic spin is

where g is the Landé g-factor.

Since spin magnitude allows only up or down spin states,

As the Landé g-factor is equal to 2 to within two decimal places, it is often a sufficient approximation to take

μ = μ_B and .
