An eddy current separator is a machine used to separate non-ferrous metals, like aluminum and copper, from other materials in recycling and waste processing. It works by using a fast-rotating magnetic drum that creates changing magnetic fields. When non-ferrous metals pass over it, the shifting field induces eddy currents inside the metals, which generate their own magnetic fields that oppose the original one. This causes the metals to be repelled and thrown forward, while non-metallic materials
