Enamel Copper Wire

Enameled copper wire is popularly called magnet wire because these wires are coated with an insulation layer. The enamelled copper wire finds extensive use in the making of motors, inductor, hard-disk head actuators, and a variety of applications which demand tight coiling of insulated wires. Both aluminum and copper wires may be enameled when used for machines like transformers and motors. This insulation is provided with a thin varnish layer which is referred to as the enamel.
