Etymology

Origin of magnetic moment

First recorded in 1860–65

Example Sentences

Instead, their magnetic moments remain strongly quantum-entangled and in constant collective motion at temperatures close to absolute zero, producing behavior that resembles emergent quantum electrodynamics.

From Science Daily

These emission lines can split into several components in the presence of a magnetic field, caused by the interaction between the internal magnetic moments of the emitting atoms and molecules with the external magnetic field.

From Salon

In helical magnets, the directions of the atomic magnetic moments are ordered in a spiral.

From Science Daily

While ferromagnets, which we all know from refrigerator magnets, have all their magnetic moments aligned in the same direction, antiferromagnets have alternating magnetic moments.

From Science Daily

Traditionally, the material has been regarded as a classic antiferromagnet because the magnetic moments on neighbouring manganese atoms point in opposite directions, generating a vanishing net magnetisation.
