Magnetic flux control idea

[Low-Q]

Spinning an all north field, creates a south field out in front of the spinning north
The distance away from the spinning field, determines on the strength of the magnet's that are spinning

Just mount a retainer on either side to prevent the rods from traveling too far.
Nice work

I do not understand the first paragraph


Retainers will help , bu I'll try this holey rod holder first.

Then the structure to hold the shafts and the shields is finished. Not good quality since I printed too fast, too low temperature. Anyways, it holds the wheels and shield good enough.
The flexible rod holder didn't worked, so I'm printing two 15° cones that holds the rods. These cones fits between the wheels, and will roll along the inside without wobbeling from side to side.
I also have to make a stronger magnet. Stacking those discmagnets, and configure them as an hallbach array. I will show you how later.
Here is a couple of new pictures.

I'm not sure if these are any help to you, but Laithwaite has many videos on youtube, that gave me many ideas on magnetics

I watched the video in your link. Very interesting stuff. If I just could get my magnets to behave like AC-coils.

New update on the project. It didn't worked out as I hoped. So new parts is printed to achieve better alignment and much less friction.
As said before, the exposed rods at the narrow side was assumed to be pulled more than the hidden rods at the wide side, where I also could not figure out what counter force which stops the rotation. However, some misalignments, and too short rods, prevents a good analysis of whats going on.
Here is a short video, in poor slow english ( )...
