FIELD: education; educational aids.
SUBSTANCE: surface, which separates electrically conducting matters, is placed inside space of magnetic circuit. Alternating current is passed through the surface. Component with first harmonic frequency is selected from oscillations of magnetic field, which component has phase shift of ¼ period relatively the harmonic. Amplitude of alternating component of surface circular current is revealed from phase shift direction during one of half-periods as well as polarity of surface magnetic moment is found which moment is created by the component during the same half-period. According to another version of the method, surface circular current is found from emf of induction coil put onto the magnetic circuit and component of emf is selected which coincides in phase with current through surface or the component being opposite in phase to current. Experiments demonstrated reveal property of double electrons with parallel spins to create mated dipole moments, namely electric and magnetic ones. Device has magnetic circuit with space inside which space the dish is placed. Two parallel electro-conducting plates are disposed as well as electrolytic solution. Separator provide with window is disposed between the plates. Inductance coil and reference frame are put onto magnetic circuit. Plates are connected to secondary winding of transformer connected with ac generator. Winding is connected with ancillary electrode though additional current source. Inductance coil is shunted y capacitors unit to form resonance circuit.
EFFECT: demonstration of magnetic degree of order of aoms onto surface of matter.
