- noun
- /mæɡˈnɛtɪk ˈdaɪpoʊl ˈmoʊmənt/
- Specialized
- In her experiment, the researcher calculated the magnetic dipole moment to analyze the effect of the magnetic source.

- Each proton has a magnetic dipole moment.
Examples
-
The magnetic dipole moment of the particle determines the strength of the magnetic field it generates.
-
Axial magnetic dipole moment induced in the Madison Dynamo Experiment.
Academic text (2006) -
After adding the usual interaction between the magnetic field B and the magnetic dipole moment (S/S) of a particle with spin S, and then expressing terms in a nonrelativistic form, one finds that the Lorentz-violating background couples to spin much like a magnetic field does.
Academic text (2004) -
Scientists measure the magnetic dipole moment to understand how certain particles interact with magnetic fields.
Synonyms
A measure of how strongly something turns near a magnet and which way it points
A measure of how strongly and in what direction a magnet turns in a magnetic field

Morphology
The compound is transparently compositional: 'magnetic' (relating to magnetism) + 'dipole' (two opposite poles) + 'moment' (a quantitative measure) together yield the idea of a measure of a magnetic dipole's strength and orientation. Although it is a technical physics term, the constituent meanings directly lead to the MWE meaning, so a learner who knows the parts can infer it.
Etymology
Magnetic dipole moment comes from the image of a tiny magnet: magnetic means 'about magnets', dipole means 'two ends', and moment means 'turning power'. So, it describes how strong and which way a small magnet or a loop of electric current will point or turn when near a magnet.
