noun

1. Also calledBohr magneton a unit of magnetic moment equal to eh /4π m 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 ^–24joule per tesla βmB
2. Also callednuclear magneton a similar unit equal to β m / M where M is the mass of the proton

magneton

/ măg′nĭ-tŏn′ /

1. A unit of the magnetic dipole moment of a molecular, atomic, or subatomic particle.
2. ◆ 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.
3. Also called Landé factor
4. ◆ 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.
