FIELD: measuring equipment.
SUBSTANCE: invention relates to the field of measuring technology and magneto-electronics and can be used to study the processes of rotational motion of electrons in a vacuum under the action of a pulling electric field with thermionic emission and a magnetic field, whose vector is orthogonal to the electron flux (that is, it is orthogonal to the electric field vector). Device includes a vacuum vessel in the form of a disk with a thermocathode centrally located together with the rotational axes and a ring anode at the periphery of the vessel, which are connected to a source of high constant voltage and to the source of the thermal cathode heater through three sliding contacts, two of which are connected to the conducting semiaxes, and the third to the annular anode. Vessel of a dielectric material, for example glass, is rigidly bound by its lateral faces to a pair of toroidal magnets mounted coaxially and facing each other with opposite magnetic poles.
EFFECT: technical result consists in providing the possibility of carrying out studies of the "Faraday paradox" when replacing a nonmagnetic conducting disk with a vacuum, that is, in the absence of a crystal lattice, with which electrons interact, exerting pressure on it by the arising Lorentz forces.
