Magnetic Moment

</dt>
1. The quantity obtained by multiplying the distance between two magnetic poles by the average strength of the poles. </dd>
2. A measure of the magnetic flux set up by the gyration of an electric charge in a magnetic field. The moment is negative, indicating it is diamagnetic, and equal to the energy of rotation divided by the magnetic field. </dd>
3. (symbol m). In atomic and nuclear physics, a moment, measured in Bohr magnetons, associated with the intrinsic spin of the particle and with the orbital motion of the particle in a system. Also called magnetic dipole moment. [[/a>|/a>]] </dd>
