Also called Bohr magneton. a unit of magnetic moment equal to eh/4πm where e and m are the charge and mass of an electron and h is the Planck constant. It has the value 9.274 096 × 10–24 joule per tesla β, mB
2.
Also called nuclear magneton. a similar unit equal to βm/M where M is the mass of the proton
(māg'nĭ-tŏn') A unit of the magnetic dipole moment of a molecular, atomic, or subatomic particle. ◇ The Bohr magneton is defined as the magnetic dipole moment of the electron due to its inherent spin angular momentum, and is equal to 9.2741 × 10^{-24} joules per tesla. Also called Landé factor. ◇ The nuclear magneton is defined using the electric charge and rest mass of the proton, and is equal to 5.0508 × 10^{-27} joules per tesla.
