Magnet wire, or enameled wire, is a copper or aluminum wire covered with a very thin layer of insulation.

Q: Why is copper wiring safer than aluminum wiring?

Q: What's the difference between an enameled aluminum wire and an enameled copper wire?

Comparison of Different Metal Conductors

Winding or coil - a length of wire or conductor wound in a specific shape, in order to achieve specific magnetic, electric or electromagnetic properties of such configuration.

Enamelled wire is a metallic conductor insulated with a varnish and generally used for electrical applications.

Enamelled wire with  is widely used in windings of small and medium size electric motors and transformers, as well as other electromagnetic devices such as sensors and actuators.

For definitions, general notes on methods of test and the complete series of methods of test for winding wires, see IEC 60851-1.

Painting is the process of applying enameled wire enamel to a metal conductor to form a uniform paint layer with a certain thickness.

Solderable insulation is a special film insulation that is used on magnet wire in low cost, high volume applications.The magnet wire, with this solderable insulation,is wrapped around the terminal or pin.

The major application areas are electrical and electronics, automotive, medical and aerospace.

In rare cases pin holes develop at wire enamaltion as film thickness decreases. At PVF contact with water and/or solvent can increase number of such pin hole probability as microscopic can result under echanical stress by bending and/or stretching.
