Magnetic Copper Wire

SKU: CU805100 Category: Tags: , ,

Enameled Copper Wire, Magnet Wire or Magnetic Wire is a copper wire coated with a very thin layer of insulation. It is serves as an electrical conductor in motors, inductors, speakers, transformers and other electromagnetic equipment, and allows multiple layers of wire to be wound together without short circuiting.When wound into such a coil and energized, the magnet wire creates an electromagnetic field.

The core wire itself is most often fully-annealed, electrolytically refined copper, which allows for closer winding when making electromagnetic coils. The insulation is made of tough polymer film materials rather than enamel, as the name might suggest.The copper wire is not coated with a layer of enamel paint or vitreous enamel (made of fused glass powder). Modern magnet wires typically have one to four layers of polymer film insulation, often of two different compositions, to provide a tough and continuous insulating layer. Magnet wire insulating films tend to use Polymers such as Polyvinyl Formal (Formvar), Polyurethane, Polyamide, Polyester among others.

Magnet wire plays a crucial role in three areas of energy transformation–from electrical to electrical, from electrical to mechanical, and from mechanical to electrical. In addition to this use in energy transformation, magnet wire is critical to a wide range of communications applications. It is used in coils in products such as computers, cell phones, telephones, video games and televisions. Magnet wire is generally available in many sizes and temperature ratings.
