Magnets installed in the waste heat fan, the power can also light the bulb

- Nov 22, 2017 -

First, prepare an old computer cooling fan and affix a circular magnets to each blade. Then a neodymium magnet was prepared and placed on the edge of the heat sink, rotating the blades without electricity due to the same principle of repellency. Then, an energy-saving light bulb was also prepared and connected to the power cord on the cooling fan with a power cord. Then, the neodymium magnet is placed on the edge of the cooling fan again, and after the blade is repulsively started to rotate, the bulb connected to the power cord starts to emit light while the blade rotates.
