WebBuild a generator with magnets: Using Faraday's law of electromagnetic induction. If you want to increase the efficiency of your magnet generator, you can use rare-earth neo supermagnets instead of ceramic magnets. With these stronger magnets, you'll only need about 40 turns of wire to generate enough electricity to power a small device. WebSo does the bulb light up when there's a changing magnetic field because: a moving electromagnetic field will exert a force on the free electrons of a wire to move; moving electrons is the definition of current; thus the bulb lights up. The force applied depends on the direction of the changing magnetic field, thus changing the way current flows.
