Eddy Current Separator

In magnetics, an eddy current is created when a conductor and the magnetic field source are moving relative to each other. This relative motion causes a changing magnetic field that generates a magnetic flux counter to that created by the magnetic field. The result is a repulsive force between the magnet and the conductor. An eddy current separator makes use of this magnetic reaction to remove non-ferrous metals from magnetic metals, usually in conjunction with a converyor belt system transporting the mixed material.
