- e is the elementary charge,
- ħ is the reduced Planck constant,
- mp is the proton rest mass, and
- c is the speed of light
In SI units, its value is approximately:
Due to the fact that neutrons and protons consist of quarks and thus are no real Dirac particles, their magnetic moment differ from :
The magnetic dipole moment of the electron, which is much larger as a consequence of much larger charge-to-mass ratio, is usually expressed in units of the Bohr magneton. The Bohr magneton, which is calculated in the same fashion as the nuclear magneton, is larger than μN by a factor equal to the ratio of the proton to electron mass, or about a factor of 1836.
