FIELD: physics.
SUBSTANCE: educational device has a support, an unlabelled magnet, a compass, a magnet support, a voltmeter, an ammeter, a milliameter and an educational power supply VU-4. Ends of connecting leads are provided with plugs. The sliding block is in form of a rod made of nonmagnetic material. A set of magnets is mounted at one end of the rod and a limiting washer is placed at the other end. A guide for the sliding block is in form of a magnetically conducting polyethylene transparent tube with arresters. A pendulum is in form of a bobbin. The winding wire is provided with a label for the direction of winding. The ends of the winding wire are connected to extension leads whose free ends are provided with plugs. The extension leads pass inside a tubular rod made of nonmagnetic material, one end of which is connected to a coil and the free end is provided with a suspension hole.
EFFECT: improved device.
