Wind power is the conversion of wind energy into mechanical or electrical energy, by using wind turbines to make electrical power, windmills for mechanical power. This kit is to demonstrate the generation of electric energy by a  wind energy (kinetic energy) or generation of electricity by moving a coil in a magnet. When air strikes the generator blade, it turns the coil of small generator to produces electricity and lights up a LED and a connected voltmeter indicates the amount of current being  produced by the generator.
