FIELD: physics.
SUBSTANCE: invention relates to theoretical and experimental physics. In the method, a device for demonstrating the rotation of free electrons in a closed system contains a pair of toroidal permanent magnets facing each other with opposite magnetic poles, as well as a DC power supply. In the magnetic gap between the permanent magnets there is a hollow vacuum-evacuated glass disk with two semi-axes of its rotation, in the center of which there is a thermal cathode with a heating thread, electrically connected to the semi-axes and through a pair of sliding contacts with the source of the heating voltage of this filament of the thermal cathode. At the periphery of the glass disk, an annular anode is placed by fusing it into the glass of the disk, connected from the outside with a sliding contact. Also, the thermal cathode and the annular anode are connected via sliding contacts to a high voltage direct current source.
EFFECT: technical result consists in verifying the lack of counteraction forces for the acting Lorentz forces that ensure the rotary motion of closed mechanical systems under the action of only internal forces.
