El magnetón nuclear (símbolo μN), es una constante física de momento magnético, definido por: donde: e es la carga elemental,ħ es la constante de Planck reducida,mp es la masa restante del protón. En unidades SI, su valor aproximado es: μN = 5.05078324(13)×10-27 J/T El magnetón nuclear es una unidad natural para expresar los momentos dipolares magnéticos de partículas pesadas tales como nucleones y núcleos atómicos.Por el contrario, el momento dipolar del electrón, que es mucho mayor como consecuencia de un ratio carga-masa mucho mayor, se suele expresar en las unidades correspondientes del magnetón de Bohr.

The nuclear magneton (symbol μN), is a physical constant of magnetic moment, defined in SI units by: and in Gaussian CGS units by: where: e is the elementary charge,ħ is the reduced Planck constant,mp is the proton rest mass, andc is the speed of light In SI units, its value is approximately: μN = 5.05078353(11)×10−27 J/T In Gaussian CGS units, its value can be given in convenient units as μN = 0.105155 e⋅fm The nuclear magneton is the natural unit for expressing magnetic dipole moments of heavy particles such as nucleons and atomic nuclei. 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.
