In atomic physics, the electron magnetic moment, or more specifically the electron magnetic dipole moment, is the magnetic moment of an electron resulting from its intrinsic properties of spin and electric charge. The value of the electron magnetic moment (symbol μ e) is −9.284 764 6917 (29) × 10 J⋅T. ‍ In units of the Bohr magneton (μ B), it is −1.001 159 652 180 59 (13) μ B, a value that was measured with a relative accuracy of 1.3 × 10.
