The phenomenon of orientation of a magnetic needle about a conductor with an electric current (the experiment of H.Ch. Oersted, 1820) is widely known [1], as well as and the subsequent experiments of M. Faraday (1821) and А.-M. Ampere (1821-1822 ) on unbroken rotation of a magnet around of a conductor with a direct current and magnet-conductor about an own axis at passage through it of an electric current. These fundamental experiments, alongside with model of the “electromagnetic self-runner" of Aniosh Jedlik (1828), laid a basis for creation of the first electric motors and whole class of modern electric inductive machines of direct and alternating current (unipolar, collector, synchronous and others). However, here there was unnoticed one white stain, namely: a basic possibility of unbroken rotation of a «magnetic needle» near an electric current. Really, the vibrating movements of a magnetic needle at a strong enough push or periodic influences can pass in circular damped inertial movement or in the uninterrupted compelled rotary movement. So at parametrical rocking of a pendulum or a swing lever in a step with vibrations at the maximal rejection the vibrating movement on inertia passes a point of return and turns to unbroken rotary moving, just as the gymnast on a turnik under the certain conditions " twists the sun “.
In practice of navigation the continuous low-frequency circular rotation of a magnetic needle of a storm-compass in time of rocking of the ship on a wave, owing to periodic mechanical or magnetic influences (for example, because of displacement of iron bodies of a construction), is sometimes observed. The phenomenon has a character of auto-fluctuations of a resonant type passing in rotary movement, to that the works of a number of the researchers [Kolong I.P. (1880), academician Krilov A.N. (1938) et al.] are devoted. This problem is eliminated by tuning out of the own period of fluctuations of the compass card (magnetic needle) from the rocking period of the ship (about tens of seconds). It is essential, that the directing force working on a sensitive magnetic needle, is small and does not suppose any loading, for example, even the most gentle electric sliding contacts practically completely limit freedom of rotary movement of a magnetic needle of a compass or an inclinator.
It is known also, that except for low-frequency rotation, the magnetic needle can be involved in fast circular movement by a rotating magnetic field, for example, in a stator of the asynchronous or synchronous motor. Besides the continuous force rotation of comparatively massive magnets on a rotor in a variable magnetic field of industrial frequency, pulsing on one direction, for example, in single-phase synchronous motors with the fixed constructive accommodation of a magnet-rotor, is carried out. Such rotary movement of a permanent magnet around of an own axis close or at a distance from a linear electric current till now by nobody was observed. In this respect a high-speed unbroken circular rotation of the easy (low-inertia) oblong form magnetic needle on the whole practically is impossible in air or liquid, because of resistance of the medium (though such possibility is not excepted in the vacuum) and, especially, near to a conductor with a current, because of an attraction in an inhomogeneous magnetic field as body with strongly expressed anisotropy of the form.
However, and two centuries is not yet passed from the moment of the fundamental discovery of Oersted (1820 + 182 = 2002) or that is equal to the tenth part of the time period from Christmas, as the searched effect of unbroken rotation of a magnet near a linear current was found out experimentally in 2002 in various variants [2. 3], as for an alternating current of industrial frequency (01.01.2002), so and for a direct (rectifiered) current (31.12.2002). At switching on of a current the free-supported permanent magnet of the rectangular form independently comes in movement and drives up to speed in some thousand revolutions in one minute and continuously rotates (without noise and vibration) close and at a distance up to 10 centimetres and more from a linear conductor with a current in air. Such rotation and it other variants provide an possibility of free placement and displacement of a rotor-magnet or a group of the rotors with force application as the motor for changing of rotary movement in translation along a conductor with a current at feeding of energy without a contact or as the electromechanical transducer, the device of a take-off or storage of electric energy. The priority of the found out effect is confirmed by the Patent BY 846U (Republic of BELARUS) on useful model “Device of rotation of a magnet near a linear current" [2]. Except for unbroken rotary moving of a single magnet in experiment the similar movement of a composite rotor-magnet with various speed is realized, and also all experimental results are repeated at unilateral influence of a magnetic field of excitation from a multiwire loop or coil with the magnetic core on necessary distance.
Primary practical application the found out effect takes as demonstration physical model in courses of physics and electrical engineering in higher and high school in safe performance directly in air (without use of mercury, acid, the copper copperas or other liquids, in contrast to the demonstration models of the experiments of Faraday and Ampere on unbroken electromagnetic rotation) and also in other fields of electrical engineering and automatics.
In a result of the achieved new knowledge now there are convincing bases to find in a nature an example similar magnetic or electric microrotators, receiving the energy replenishment for eternal moving from the high-frequency electromagnetic wave fields, which constantly present in the world space. In any case here it is made quite purposefully and naturally the due step in a deepening of physical knowledge and in a new direction of technical progress, though and at casual successful concurrence of a number of the factors in experiment, about what and it was necessary to inform in the given article.
