Faraday Induction

Move a magnet through a pickup coil and connect changing magnetic flux to induced emf, current, and Lenz's-law direction.

This simulation references an engine behavior that is not registered.

An electromagnetic induction simulation for seeing why motion through a nonuniform magnetic field, not field strength alone, produces an induced emf. Learners tune magnet strength, speed, coil geometry, turns, resistance, and polarity while flux linkage and induced emf update together.
