Magnet wire or enameled wire is a copper or aluminium wire coated with a very thin layer of insulation. It is used in the construction of transformers, inductors, motors, generators, speakers, hard disk head actuators, electromagnets, electric guitar pickups, and other applications that require tight coils of insulated wire.

"Magnetic wire" redirects here. For magnetic wire recording, see wire recording.
"Fly-wire (wire)" redirects here. For jumper wires, see jump wire. For wire bridges, see jumper. For patch leads, see patch cable. For other uses, see Fly wire (disambiguation).
The wire itself is most often fully annealed, electrolytically refined copper. Aluminium magnet wire is sometimes used for large transformers and motors. The insulation is typically made of tough polymer film materials rather than vitreous enamel, as the name might suggest.
