TRAINING DEVICE FOR DEMONSTRATION OF SECOND MAXWELL EQUATION Russian patent published in 2006 - IPC G09B23/18 

FIELD: training devices, possible use in laboratory practicum on physics for studying physical rules and occurrences.

SUBSTANCE: device contains two even toroids, positioned oppositely and in parallel to one another at distance of their radius. Outputs of windings of toroids are connected to output clamps of sound frequency generator. Both toroids are mounted on substrate, on which scale with points is installed. Moveable platform is positioned on substrate between toroids along the scale with points. Measuring coil is mounted on moveable platform at the level of axis of toroids and at even distance from them so, that its axis coincides with direction of strength vector of magnetic field, created by electric field of toroids. Position pointer of measuring coil is positioned on moveable platform and coincides with axis of measuring coil. Input clamps of EMF registrar are connected to outputs of measuring coil. Drive with belt transmission is held on substrate and is used for moving moveable platform between aforementioned toroids along the scale with points for counting distance from axis of toroids to measuring coil with position pointer. Supporting coil is mounted on the substrate between toroids at the level of their axis and in parallel to measuring coil at distance from axis of toroids, equal to their radius. Device contains device for measuring phase difference, first input of which is connected to outputs of measuring coil, and second output - to outputs of supporting coil. Device allows measuring dependence of shift current from frequency and strength of electric field. On basis of indications of phase difference meter it is possible to demonstrate right-handed screw system between vectors of shift current density and magnetic field strength.

EFFECT: expanded research area, increased precision of measurements.
