magnetic moment

 
–noun Electricity.
a vector quantity associated with a given electric current, magnet, or the like, having the property that its vector product with the magnetic induction equals the torque acting on the given object.
Also called dipole moment.

dipole moment  

  1. The product of the strength of either of the charges in an electric dipole and the distance separating the two charges. It is expressed in coulomb meters. Dipole moment is a vector quantity; its direction is defined as toward the positive charge.

  2. The product of the strength of either of the poles in an magnetic dipole and the distance separating the two poles. Dipole moment is a vector quantity; its direction is defined as toward the magnetic north pole. Since magnetic monopoles apparently do not exist, the magnetic moment is usually calculated by analysis of the flow of electric current inducing the magnetic field.
