In this project I built a basic reed-switch operated electromagnet. The circuit uses a 3–6 V battery, a reed switch, and a hand-wound air-core coil made with 36 AWG copper wire (about 740 turns on a small plastic bobbin). When the reed switch closes, current flows through the coil and produces a magnetic field. This is a very clear demonstration of how electricity can be converted into magnetism. To protect the circuit, a 1N5819 Schottky diode is connected in parallel with the coil in reverse bi
