Mechanism of Eddy Current Separator

The high-energy permanent magnet located inside the high-speed drum creates a strong electromagnetic induction phenomenon on the surface of the drum. When the aluminum, copper, brass and magnesium pass through this magnetic field, the eddy current occurs repelling them respective to their conductivity thereby pushing each the distance determined by Fleming’s left hand rule. The devise is useful for recycling, resource collection, and as an aluminum separator.
