FIELD: engineering of training devices, possible use in laboratory practicum for physics course to study and expand knowledge of physical laws and events.
SUBSTANCE: in accordance to invention, mounted on a table are measuring coil and model contours with current are applied. Rotation axis is positioned perpendicularly to table. First end of rod is immovably mounted on rotation axis, and onto its other end a platform if pinned movably, on which platform inductance coil is mounted perpendicularly to table. Platform and inductance coil touch the table with possible sliding across it. Immovable contact of rheostat is connected to second output of inductance coil. First output of winding of reducing transformer is connected to movable contact of rheostat, while its second output is connected to second input of ammeter.
EFFECT: expanded functional capabilities and increased precision of measurements.
