Permanent magnet generator with no relative motion between magnet and coil

Simple generator provides enough power to light led’s. There is no relative motion between the permanent magnets and the coil. Instead we open and close the “magnetic circuit” between the magnet and the coil, causing a change in the coil flux, which induces a voltage in the coil by Faraday’s law. Magnets are ceramic/ferrite. Coil [...]
