The nuclear magneton (symbol $\mu_\mathrm{N}\!$ ), is a physical constant of magnetic moment, defined by:

$\mu_\mathrm{N} = {{e \hbar} \over {2 m_\mathrm{p}}}$

where:

$e\!$ is the elementary charge,

$\hbar$ is the reduced Planck's constant,

$m_\mathrm{p}\!$ is the proton rest mass

In the SI system of units its value is approximately:

$\mu_\mathrm{N}\!$ = 5.050 783 24(13) × 10^-27 J·T^-1
