Designed to investigate the dependence of the direction of induction current on the nature of the change in magnetic flux that causes the current in the following demonstrations:

Comparison of the interaction of a solid contour and a ring with a slit with a magnet;

motion of a solid ring as the magnet approaches the ring;

motion of the solid ring when the magnet is pulled out of the ring.

The device for studying Lenz's rule is a stand with a shaft (150 mm long) and two aluminum rings, one of which has a slit.

Suggested Experiments:

- Comparison of the interaction of a solid contour and a ring with a slit with a magnet,

- motion of a solid ring as the magnet approaches the ring,

- motion of the solid ring when the magnet is pulled out of the ring.

The principle of operation of the Lenz device is based on the interaction of a circuit with an induction current and a magnet whose motion is the cause of the current. The demonstrations require a strip magnet or a stack of ring magnets.
