Magnetic Rotor Answered

How does this device work? Has it ever been on instructables or anything like it? How would I go about mounting the magnets on the rotor? What sort of spring would I need for the magnet mounted to the vertical shaft that slides up and down? In short I want to know every little detail about building it before I begin so I don't go buying a lot of unecessary stuff and waste money.


It runs on the same principle of a gauss gun.
You can get these things to run for a long time but none have passed the run for one year test and few can do the littlest task for a short time.
There are some videos there that are just plain trickery.

I don't get it - where's the "perpetual motion", as claimed in the video title?
