Abstract: The expression for mean force exerting on a conductor ring in alternating magnetic field is derived. The direction of the force in alternating magnetic field of magnetic dipole is discussed, and the relationships between the force and frequency to, the ring's self-inductance coefficient L are investigated.

Key words: alternating magnetic field, conductor ring, floating ring demonstration, mean force, magnetic dipole
