Elementary Knowledge of the Magnet Wire

2017-05-11

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, speakers, hard disk head actuators, electromagnets, and other applications that require tight coils of insulated wire.

Magnet Wire

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 enamel, as the name might suggest.
