Eddy current formation is a fascinating phenomenon that occurs when a conductor, like aluminum, moves through a magnetic field. As the aluminum plate spins, it cuts through the magnetic field, causing circulating currents—called eddy currents—to form within the metal. These currents generate their own magnetic fields, which oppose the original magnetic field of the nearby magnet. This creates a repulsive force strong enough to make the magnet appear as if it’s floating. The faster the aluminum r
