    When a magnet is dropped down a metallic tube, the changing magnetic field created by the falling magnet pushes electrons around in circular, eddy-like currents. These eddy currents have their own magnetic field that opposes the fall of the magnet. The magnet …

  • Eddy Current Systems | Bunting - Redditch

    An eddy current separator is a dual pulley conveyor system, where the non-metallic rotor cover houses an independently rotating high-speed magnetic rotor. Separation occurs when a non-ferrous metal particle (e.g. aluminium, copper or zinc) is conveyed into the magnetic zone. The non-ferrous metal particle is exposed to rapidly changing magnetic ...
