magnetic moment

Noun

Meaning

the torque exerted on a magnet or dipole when it is placed in a magnetic field

Synonyms

Hypernyms

Examples

Antiferromagnets have a zero net magnetic moment, meaning no field is produced by them. Source: Internet

Attempts have been made to quantitatively recover the neutron magnetic moment from first principles. Source: Internet

Because the electron is charged, it produces an orbital magnetic moment that is proportional to the angular momentum. Source: Internet

Caution: in part because there are not enough Roman and Greek symbols, there is no commonly agreed-upon symbol for magnetic pole strength and magnetic moment. Source: Internet

Fields of a magnet Far away from a magnet, the magnetic field created by that magnet is almost always described (to a good approximation) by a dipole field characterized by its total magnetic moment. Source: Internet

For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, Knight, Jones, & Field, "College Physics" (2007) p. 815 and the magnitude relates to how strong and how far apart these poles are. Source: Internet
