A Greek mu with a capital B subscript, the electron's magnetic unit.
Also known as: Bohr magneton, Mu B, Electron magnetic moment unit
The Bohr magneton is the natural unit of magnetic moment for an electron. An electron's actual spin moment is about twice it, and the small excess over exactly twice — the anomalous magnetic moment — is the most precisely tested prediction in all of physics.
Denotes the Bohr magneton, the natural unit of magnetic moment for an orbiting or spinning electron.

Relates to the electron's actual magnetic moment through the g-factor, whose measured departure from 2 is the anomalous magnetic moment.
