Magnet wire is copper wire with a thin layer of insulation which protects the coiled wire from short-circuiting. With its easy solderability, high thermal resistance, and attractive enameled sheen, magnet wire finds use in a large variety of applications including transformers, wound coils, motors, relays, solenoids, instruments/guitar pickups, and arts & crafts. This magnet wire meets the NEMA MW 79-C or MW 80-C standard for operating temperature (155°C / 311°F) and insulation makeup.
