Bohr magneton
In atomic physics, the Bohr magneton (symbol ) is a physical constant and the natural unit for expressing the magnetic moment of an electron caused by either its orbital or spin angular momentum.
The Bohr magneton is defined in SI units by
:formula_1
and in Gaussian CGS units by
:formula_2

where
: is the elementary charge,
: is the reduced Planck constant,
: is the electron rest mass and
: is the speed of light.
