IEVref: 221-05-03 ID: Language: en Status: Standard Term: gyromagnetic coefficient (of an electron) Synonym1: gyromagnetic ratio (deprecated) [Preferred] Synonym2: Synonym3: Symbol: γ Definition: of an electron in a gyromagnetic substance, the quotient of the magnetic area moment due to spin by the angular moment of the spin NOTE 1 – The angular precessional frequency ω of an electron is related to the applied magnetic field H by the expression: ω = γ μ0 H where μ0 is the magnetic constant and γ is the gyromagnetic coefficient. NOTE 2 – For a free electron the gyromagnetic coefficient approximately equals: 176 × 109 C kg−1.
