Definition

angular frequency (ISO 80000-3: Space and time) of the electron angular momentum (ISO 80000-4: Mechanics) vector precession about the axis of an external magnetic field:

ω_{L} = \frac{e}{2 m_{e}} B

where

$e$ :: is the elementary charge (ISO 80000-1),

$m_{e}$ :: is the rest mass (rest mass) of electron, and

$B$ :: is magnetic flux density (IEC 80000-6: Electromagnetism)

pulsation (ISO 80000-3: Space and time) de précession du vecteur moment cinétique (ISO 80000-4: Mechanics) d'un électron autour de l'axe d'un champ magnétique externe:

ω_{L} = \frac{e}{2 m_{e}} B

où

$e$ :: est la charge élémentaire (ISO 80000-1);

$m_{e}$ :: est la masse au repos (rest mass) de l'électron; et

$B$ :: est l'induction magnétique (IEC 80000-6: Electromagnetism)
