Science definitions for magneton


[ măgnĭ-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 X 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 X 10-27 joules per tesla.
