@Magnetman,


Please upload the latest test video.

Magnetman, this is pretty complicated and will likely not be replicated. Furthermore if it works, then likely only with a certain magnets, every detail in that setup matters.

Your upper ring magnet floats freely on the lower one?

If so, interesting is, if we made these ring magnets a slightly cone shape, were it then a completely friction free bearing?


You can use a 12 oz tall inexpensive plastic drinking glass for the 2 inch pvc pipe and cement it onto the plastic block under it.   Yes the large ring magnets repell each other and very little friction is the result in the top magnet spin on a simple bearing.  It free floats.

Here is a video of my setup turning without the pvc pipe. I used the plastic tube with two rod
Magnets inside it. I am waiting for some tall plastic drinking glasses to put the rod magnet tubes inside.
As you can see it turns by almost touching the rod magnet tube anywhere near the block the drinking glass will be cemented to.    Polarity as shown on my diagram.      Tom

Just sticking disc magnets to the side rim of the upper disc would generate the same repulsion!

I used two large ring magnets and a total of 8 rod magnets will be used.  What's with the ""disc" magnets?  Show how?
