It resolves itself into equally-charged electrons; we have also now the magneton, or atom of magnetism.
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.
