A magnetic rotator ('magtator') is a free-support rotor-magnet for a rotary-translation motion with the distant uncontact transfer of energy from an external magnetic field. Generally, a magnetic rotator is a rotating magnetic dipole. The unbroken synchronous rotation of a rotor (one or several magnets) close and at a distance from a linear conductor with an alternating and direct current (the experiments of Sidorovich A. M., 2002) is a first example of magnetic rotator with permanent magnet on rotor, as a modification of the known Oersted’s experiment (the Oersted’s discovery) of 1820 year. < http://sidam.at.tut.by > < http://www.squidoo.com/E_M_rotation >
