[Mr_Video]

did you notice how carefully he put the base (stator) on the table top ?

as if he had to position it in juuust the right spot .
maybe something under the table ?

looks easy to replicate though, I hope CLaNZeR can make it work .

Slanted magnets are interesting. I wonder what it would be like if the magnets were mounted through a Mobius ring?

A close up.
Seems its not necessary to place magnets very very accurately. Some magnets have different gaps and heights don't vary uniformly. Even the slanting is just approx.

So it would be easy to try without further info. The stator can be S-S, N-N or S-N.
One can even interchange stator and rotor and place the magnets on a base and use stator as rotor, should be easier.

I onece view a similar device (not same construction) using the magnets at different heights. It ran well but slowed down. However there are some significant variations on this. I will sit on the fence until its been replicated

@ All

I didn't realize this yesterday when I posted the above pictures from Youtube but this is being covered at Peswiki with more pictures and details.

See http://peswiki.com/index.php/OS:Magnet_Motor_by_FM_Concepts

If you scroll down the page to the Instructions section you will see the following explanations of the reason for the slanted magnet arrangement.

To better understand, try first to actuate the rotor with only one magnet in repulsion by hand. After this, try to displace the actuator magnet away from rotor to surpass the magnetic gate and return to face to face in ramp. You see the attraction of the other side of rotor’s magnets when you displace away the actuator. In the middle of magnets, the force field is closest to neutral. After try to make measurements in the required displacement to surpass the magnetic gate. A lot of patience is required to make the correct evolution in the deflected angle, step by step, until achieve the correct progressive deflection.

The key is: convert the repulsion in magnetic gate into attraction (great angle), decrease the attraction when the magnetic field is diminished (small angle), and restart the repulsion again in the ramp.
