This mi idea

And in the gland to check it is weak?

Lead does not shield magnetism. Just saying.

  But have to admit, non magnetic and will roll with the flow. Gravity will have a definite effect on it. A few mags and 3  3D printed plates with slots in the middle would make it. Doubt that one slot could make it spin. Three, well who knows.  Think its a fun project to play with.  Now, where to find .5" lead ball bearings?

Hi Vidar,
Indeed,  lead does not shield magnetism. 

Here is the animation of his setup: https://www.youtube.com/watch?v=CldtzxgcrQg   

(The repel-out force at around the 5 o'clock position when rotor magnet is kicked out should be high enough to be able to lift up the ball as high as the 12 o'clock position of the ball, to have chance for making another rotor revolution. 
The ball have a certain motive energy gained from the fall from about 8 o'clock towards 6 o'clock, this energy adds to the kick-out force. )

EDIT :  I just read the inventor's comment below the video and he wrote to somebody the setup is shown from top view. This means the rotor disk is horizontal so the "modus operandi" differs from what I wrote above: no gravity involved.
So it is the inertia of the moving ball which pushes the rotor magnet through the sticky repel point at the moment of entering the stator magnet ramp (at around the 10 o'clock position).  The ball received its kinetic energy from the kick out force the moment the rotor magnet leaves the stator ramp.

Interesting setup,  should be tested to say whether it is able to operate continuously or not.
