Copper enamelled wire with coil included What you get Copper enameled wire with the coil included for immediate use in winding projects. important measurement notes The diameter specified in the enameled wire specifications refers to the bare copper wire, not including the paint insulation. When measured with a gauge, the diameter is the outer diameter including the enamel insulation, and this measured size is usually larger than the specification standard. coil included The product in this listing is a copper wire and the coil is included. color and size options Coils are available in different colors and sizes. size advisory Copper wires of 1.3 mm and above are relatively thick and cannot be straightened after winding. practical applications Good for winding coils in transformers, motors, inductors, and electromagnets. Also suitable for hobby projects that involve coil winding and learning about enamelled wire behavior. use scenarios 1) Building or repairing small transformers, inductors, or electromagnets for electronics projects. 2) Winding coils for hobby motors or solenoids used in DIY devices. 3) Prototyping and testing electronic circuits that require enamelled copper coils. guidance When selecting wire, consider that the outer diameter (with enamel) may exceed the nominal bare copper diameter, and plan winding accordingly.
