Magnet wire/winding wire is an insulated copper or aluminum electrical conductor used in motors, transformers and other electromagnetic equipment. When wound into a coil and energized, magnet wire creates an electromagnetic field.

Magnet wire plays a critical role in three areas of energy transformation: electrical to electrical, electrical to mechanical, and mechanical to electrical.

Electrical to electrical transformation involves transformers, which are used to transfer power. Transformers are used for power generation by utility companies, for power voltage conversion, and in electrical controls in industrial and home uses.

Electrical to mechanical transfer is necessary for motorized appliances, automobiles, industrial machinery, and residential and commercial HVAC systems. Magnet wire is a key component in each of these applications.

Mechanical to electrical transformation occurs when machine power is converted into electricity. This type of transformation includes generators, which turn mechanical power into electrical energy through the use of magnet wire.

Besides its uses in energy transformation, magnet wire is vital to a wide range of communications applications. Magnet wire is used in coils in products such as computers, telephones, cell phones, video games and televisions.
