Hand Crank Generator
Generating your own electricity by hand is a fun and educational project that teaches basic physics principles. This Hand Crank Generator project demonstrates the conversion of mechanical energy to electrical energy.
Electricity generators are based on principles of magnetism discovered by physicist Michael Faraday in 1831. Faraday discovered that passing a conductive wire through a magnetic field produced an electric current in the wire. By spinning a coil of wire around a magnet, we can create a steady current. It converts energy used to spin the coil into electrical energy.
