The copper magnet wire used for the winding of electrical equipment is called enameled wire (sometimes called motor wire or winding wire). Simply put, enameled wire is used to exchange electrical and magnetic energy. The most common enameled wire is the copper insulated wire used in electric motors-one of the greatest inventions ever made, on wheels and light bulbs. Magnet wires can be divided into broad categories, including enameled wires, coated (or service) wires, or a combination of the two.

round enameled wire types can vary, but will include the following characteristics: (a) insulation uniformity, (b) good electrical properties such as dielectric strength and insulation resistance, (c) resistance to mechanical stress, (d) resistance to chemicals , Solvents and encapsulation varnishes, (e) heat resistance and (f) long thermal life. Any enameled wire should exhibit strong characteristics in one or more of these characteristics. Each type has its own advantages and disadvantages. The main idea is that electric current generates a magnetic field. Therefore, when selecting a wire type for any particular application, operating conditions are critical.
