What is the term for wire insulated with enamel coating?

The term for wire that is insulated with enamel coating is indeed magnet wire. This type of wire is specifically designed for use in electromagnetic applications, such as in motors and transformers. The enamel coating provides effective insulation, allowing the wire to be wound tightly into coils without the risk of shorting out between the turns or with other components.

Magnet wire is typically made from copper or aluminum and is essential in applications where a strong magnetic field is necessary. The insulation not only protects the wire but also helps in maintaining the efficiency of the electromagnetic device by minimizing energy losses.

In contrast, power wire, control wire, and signal wire refer to other types of wiring employed for transmitting electrical power, controlling devices, and carrying signals, respectively. These wires utilize different insulating materials and designs suited to their specific functions, and do not typically feature the enamel coating characteristic of magnet wire.
