The wire used for winding in electrical equipment is called magnet wire (sometimes called motor wire or winding wire), and copper magnet wire is common. In the simplest terms, electromagnetic wires are used to exchange electrical and magnetic energy. The most common magnet wire is the copper insulated wire used in electric motors. This is one of the greatest inventions ever made, right next to the wheel and light bulb. Magnet wire can be divided into several categories, including enameled wire, covered wire (or winding wire) or a combination of both.
The types of magnet wires can vary widely, but they have 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 and solvents , And encapsulate varnish, (e) heat resistance, and (f) longer thermal life. Any electromagnetic wire should exhibit strong performance 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, for any particular application, operating conditions are critical to the selection of wire types.
