Winding wires, or magnet wires, are the wires used to construct coils in electronic components (transformers, relays, etc.) that generate the component’s magnetic field. These wires are primarily composed of a copper or aluminum conductor with a very thin layer of insulation. The insulation layer is as thin as possible to keep the wire cross-section small making it possible to squeeze the highest number of windings in the motor. Whereas most electrical wires are cylindrical, winding wires often have a rectangular cross-section profile; this allows for maximum cross-section during winding, thus reducing potential losses.
