32 AWG wire (0.2019 mm diameter) is a common magnet wire size for winding small transformers, inductors, and relay coils. It is used in guitar pickup windings, small motor armatures, and electromagnetic coils in sensors. Enameled 32 AWG is widely available from electronics suppliers.
32 AWG wire has a diameter of 0.2019 mm (201.9 µm), which is roughly 2.9× the thickness of a human hair (about 0.07 mm). Its cross-sectional area is just 0.032028 mm². At this size, the wire is too fragile for manual handling in most cases and is typically wound by machine as enameled magnet wire.
