Cool demonstration of Lenz’s Law 🧲 Lenz’s Law launches the ring because when a changing magnetic field is created (like by turning on the current in a coil), it induces a current in the nearby ring. The induced current in the ring creates its own magnetic field that opposes the original magnetic field. This opposition creates a repulsive force, which pushes the ring away. #science #physics #chemistry #scienceexperiment | Imagination Station Toledo
