Lenz's Law

Lenz’s law - Explained

L enz’s law – Statement The direction of an induced e.m.f. is always such that it tends to set up a current opposing the motion or the change of flux responsible for inducing that e.m.f.

Lenz’s law equation Lenz’s law is based on Faraday’s law of electromagnetic induction. The combined equation for these two laws are:

Experiment explaining Lenz law

Experiment explaining Lenz law When a bar magnet is brought closer to the enclosed ring, it is repulsed by the magnet. In this case, the induced current resists the further change increase in magnet flux. When the magnet is pulled back, the ring is attracted by it. In this case, the induced current resists the decrease in magnet flux.
