Review on BNTECHGO 26 AWG Enameled Copper Wire - Magnet Winding Wire - 3.0 lb - 0.0157" Diameter - Red Color - Temperature Rating 155℃ - Ideal for Transformers and Inductors by Jeff Morris

Great stuff, enamel holds up well. Spool kind of gets tangled if you have too much tension on it while winding. Use care, and you will be happy. I wrapped this wire in tight coils around a cardboard tube and glued it stiff. By connecting it to the subwoofer leads in my stereo I.was able to crank up the power, and when passed over a splinter of metal in my skin the fluctuating magnetic field let me feel where they were so they could be removed. I'm happy!
