Magnet wire or enameled wire is a copper wire coated with a very thin layer of insulation. It is used in the construction of transformers, inductions, motors, speakers, hard disk head actuators, electromagnets, and other applications that require tight coils of insulated wire.
The wire itself is most often fully annealed, electrolytically refined copper. Copper 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.It finds use in applications which need insulated wires that are tightly coiled. You can use the coating on copper wires. The main reason for using this coating or Ã¢ÂÂenamelÃ¢ÂÂ is to prevent the wire from getting caught in accidental short circuits.
