Excellent Shelly
Thanks for sharing
Will these magnets from hard drives be available in the hardware store or these are of a specific type to be bought in a computer store |

@ Pio..
Hard drive magnets are not mandatory to use here. You can use any powerful rectangular magnet. A power full magnet would make the fan to run in high speed and thereby giving more wind. If the magnetic power is capable to only rotate the fan, it would not serve any purpose. Try using power full rectangular magnet.
Planning to buy 4 rectangular shaped magnets and try this at home. You can purchase magnets from the shops who sells hobby kits to schools and colleges. They stock different size/shape magnets. |

No way that's gonna work. If you remember school grade science, you cannot create energy out of nothing. Even if you rotated the fan initially, friction would eventually stop it. The guy probably has lithium cells to power them......  . In perfect space with perfect lubrication, this might work. But then you don't need these magnets then. Just rotate the plastic fans and they would keep rotating if the shaft is frictionless.
For a motor, you need magnets and a coil through which electrical energy flows which creates the magnetic flux and makes the whole thing rotate. Here all you have is the magnet. |

It works. My friend tried with the hard disk magnet and it rotates continuously...
Please try it by yourself and you will know what is happening there.... |
