DEVICE FOR VERIFYING THE AMPERE LAW EXPERIMENTALLY Russian patent published in 2008 - IPC G09B23/18 

FIELD: training appliances, possible use in laboratory practicum for studying and improving knowledge of physical laws and occurrences.

SUBSTANCE: the device for experimentally verifying the Ampere law contains following parts, interconnected serially: first rheostat, switch, constant current supply, ammeter, second rheostat, electric magnet, winding of which is connected to constant current supply through the second rheostat, rectangular conductive frame which is mounted in such a way that one of its vertical sides is positioned in the gap between poles of the electric magnet, and its other sides are outside the gap, axis of rotation of rectangular conductive frame which is mounted perpendicularly to the plane of rectangular conductive frame, two rigid conductors, first ends of which are rigidly held on the axis of rotation of rectangular conductive frame, and second end are rigidly connected to rectangular conductive frame, while the first rigid conductor is connected through first flexible conductor to moving contact of first rheostat, and second rigid conductor is connected through second flexible conductor to second input of ammeter, an arrow, fastened on rotation axis of rectangular conductive frame on the same line with rigid conductors, and a scale which is graduated in degrees.

EFFECT: simplification of experimental device, reduced time and increased precision of the experiment.
