About this Simulation

This simulation models a magnet falling vertically through a copper coil tube, demonstrating electromagnetic induction and energy conversion. Learners observe how the changing magnetic flux induces currents in the coil, creating opposing magnetic fields that slow the magnet's fall—a direct visualization of Lenz's law and eddy current effects.

Learning objectives: Understand how changing magnetic flux induces electromotive force and current in conductors | Explore the relationship between magnet velocity, induced current strength, and the opposing magnetic force | Investigate energy transformation from gravitational potential energy to electrical energy and heat
