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

Lenz's Law http://physicstoys.blogspot.com/p/physics-toy-store.html A strong neodymium magnet falls slowly down a copper bus bar as though passing through a viscous liquid. Since magnetic fields pass through copper, magneview film reveals the location of the falling dipole magnet. Moving magnetic fields from the falling magnet produce electric currents in the copper. These currents then produce magnetic fields that have the opposite polarity to the initial field. So a falling magnet makes the co
