Pass the magnet through the coil to induce a voltage and current which lights the LED. The coil windings terminate in crocodile clips for easy attachment to the LED (supplied) or a meter (not supplied). Lenz’s law is demonstrated by dropping the magnet down a copper tube. The induced current produces its own field of opposite polarity to the magnet, thus slowing its rate of descent to approximately one eighth of that experienced by the non-magnetic metal slug.
