A rotating magnet generates an alternating current (AC) magnetic field that induces currents in a conductive surface. According to Lenz's law, these induced currents oppose changes in the magnetic field, resulting in a repelling force. This phenomenon is the basis for magnetic levitation (levitation) technology. The principle is effectively utilized in Maglev trains, which rely on this repelling force for propulsion and suspension. Understanding this effect is crucial for advancements in transportation technology.
