magnetic moment

Etymology: Gk, magnesia, lodestone, momentum, movement
a measure of the net magnetic field produced by an elementary particle or an atomic nucleus spinning about its own axis. Such fields are similar to the field surrounding a bar magnet and are the basis for magnetic resonance imaging.

magnetic moment

An MRI term for a measure of the net magnetic properties of an object or particle, which is a sum of the intrinsic spins of the nuclei that have an associated magnetic dipole moment interacting with a magnetic field.

magnetic moment,

n the twisting force experienced by a magnet located inside a magnetic field.
