Now we need to rotate the shaft of the generator to produce power, for that we are using Neodymium magnets which are placed on the fins of the fan as shown. These disc shaped magnets are placed in such a way that all the north poles or south poles are facing one direction i.e., inwards or outwards. These magnets facing upward produce a magnetic field. After this a larger sized magnet is faced these disc magnets [3]. This magnet also produces a magnetic field, so both the magnetic fields repel each other (like poles repel), which causes the fins to move & finally rotate the shaft of the fan (generator).
