Magnet wire, also known as enameled wire, is a type of copper wire coated with a thin layer of insulation, typically made of varnish or enamel. This insulation allows the wire to be wound into coils without the risk of short circuits, making it ideal for use in electromagnetic applications. Magnet wire is commonly used in the manufacturing of motors, transformers, inductors, and other electrical devices that require the efficient transmission of electrical current. Its key characteristics include high conductivity, flexibility, and the ability to withstand high temperatures, depending on the type of enamel coating used.
