Magnet wire is copper wire with a thin layer of insulation, and is used in a variety of applications including transformers, wound coils, motors, solenoids, and instruments. Raw copper is drawn to meet specific size requirements based on the National Electrical Manufacturer's Association (NEMA) standards. This magnet wire meets the NEMA MW 80-C standard for operating temperature (155°C/311°F) and insulation makeup. The insulation is made from modified Polyurethane with a polyamide overcoat, and protects the coiled wire from short-circuiting.

    This wire was perfect for my electromagnet. I was quite surprised with the durability of the enameled insulation. I will be ordering more soon.
