electromagnetic moment, magnetic moment

1. A measure of the magnetic strength of a magnet or a current-carrying coil, expressed as the torque produced when the magnet or coil is set with its axis perpendicular to unit magnetic flux density which is measured in ampere meters squared.

2. The magnetic moment of a current-carrying coil, equal to the product of the current, the number of turns, and the area of the coil.

3. The vector magnetic moment of a current-carrying coil, equal to the product of the current, the number of turns, and the area of the coil.

2. The magnetic moment of a current-carrying coil, equal to the product of the current, the number of turns, and the area of the coil.

3. The vector magnetic moment of a current-carrying coil, equal to the product of the current, the number of turns, and the area of the coil.

The direction is given by the right-hand rule (right hand rule) or hand rule, which refers to a current-carrying wire where the rule is that if the fingers of the right hand are placed around the wire so that the thumb points in the direction of current flow, the fingers will be pointing in the direction of the magnetic field produced by the wire.
