The nuclear magneton (symbol μ N physical constant of magnetic moment , defined in SI units by:
μ
N
=
e ℏ
2
m
p
{\displaystyle \mu _{\text{N}}={{e\hbar } \over {2m_{\text{p}}}}}
Gaussian CGS units by:
μ

m
p
c
{\displaystyle \mu _{\text{N}}={{e\hbar } \over {2m_{\text{p}}c}}}
Its CODATA recommended value is:
μ N 783 7393 (16 )× 10 −27 J⋅T−1
In Gaussian CGS units , its value can be given in convenient units as
The nuclear magneton is the natural unit for expressing magnetic dipole moments of heavy particles such as nucleons and atomic nuclei .
Due to neutrons and protons having internal structure and not being Dirac particles, their magnetic moments differ from μ N
μ p μ N
μ n μ N
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 , which is calculated in the same fashion using the electron mass. The result is larger than μ N
