Definition

EN

for a particle, vector (ISO 80000-2: Mathematics) quantity causing a change to its energy (ISO 80000-5: Thermodynamics) Δ W in an external magnetic field of field flux density B (IEC 80000-6: Electromagnetism):

Δ W = − μ ⋅ B
FR

Notes

EN

For an atom or nucleus, this energy is quantized and can be written as:

W = g μ x M B

where

g is the appropriate g factor (Landé factor or stem:[g] factor of nucleus or nuclear particle), μ x is mostly the Bohr magneton or nuclear magneton (Bohr magneton or nuclear magneton), M is magnetic quantum number (magnetic quantum number), and B is magnitude of the magnetic flux density.

See also IEC 80000-6: Electromagnetism.

FR

Pour un atome ou un noyau, cette énergie est quantifiée et peut s'écrire:

W = g μ x M B

où

g est le facteur g approprié (Landé factor ou stem:[g] factor of nucleus or nuclear particle), μ x est le magnéton de Bohr ou le magnéton nucléaire (Bohr magneton ou nuclear magneton), M est le nombre quantique magnétique (magnetic quantum number) et B est la norme de l'induction magnétique.
