I think the shielding there is completely unnecessary. It prevents moving by field lines, and also the shield attracts, preventing the radial movement of the rotor magnet. Te radial movement, i guess there are springs on the rotor magnets or something, may be a clever idea. I think they are better to implement on the stator magnets though.

Btw, having more than one stator magnet does not give any benefit there whatsoever. Because it is dynamic, every passing the rotor magnet adds speed. Multiple stator magnets may only make sense to make it more balanced, or to make the forces symmetric, like when using magnetic bearings.

So this radial movement thing only has to be implemented on one stator magnet, which makes doing it much easier. I think it would be easier to implement when to hang the stator magnet, and let it to move radially by gravity, spring is difficult to implement.

On the image below, all is such that it can be made using paper clips and mounting tape. It may also be tied with some thread, to prevent forward movement.

Sorry, this drawing was somewhat clumsy, just first what came to mind. But it was just to give an idea. What concerns drawing, btw, i have sometimes made hand drawn drawings with gimp. But i found it much more difficult than just to draw on the paper and capture it with camera.

If you mean, the magnet moves just freely, and nothing pushes it towards the opposite magnet, then that will not work, as field lines actually repulse radially.

These magnets at angle and field lines chain, are essentally the same. Magnets can be at angle. This is all about the same theory, including the reason why there seems to be overunity.

But this, enabling the magnet to move, looks like a good idea. It works only though when the negative force is repulsion and not attraction. it should prevent the magnet from going into a greater force of repulsion, by "sliding over". Maybe with a proper balance it may even increase the propulsion, one thing of the few which i have not tried. Thus good if someone would try it. One needs only one moving stator and magnets at angle, or not at angle, on rotor, so the usual "cd fan" will do.

Thank you MagnaProp for your reply, is there any type of material that could interrupt or reduce the sticking points. I have made a few improvements to the idea i will post later today or tomorrow.
Sorry I know of no such material. I don't think your new idea will work. The magnets move in to avoid the sticky spot but only do so by getting pushed in, meaning they offer some resistance. The resistance might be less but their repulsive acceleration will also be less since they only move back out when they are basically out of the stators repulsion field. Again I like your thinking though and don't wish to discourage you from attempting a build as I have never tried that idea.

Yes right, this is not any ideal solution. Maybe this is why i didn't try any moving magnets. Yet, i'm not sure that it will not somewhat decrease resistance, because when the magnet relents a bit, it does not hit the greatest force directly. Yet i think likely this still is not enough to overcome friction.

Btw, these are not "sticking points", as some may call them, it doesn't stick there, it goes over, but every time it decreases the speed.

About the magnetic shielding. First it doesn't improve anything, because it does not remove any symmetry. And it makes things worse because every shielding attracts, even mu metal attracts. That's the same as you put a piece of iron near a rotor magnet, the stator magnet attracts to this maybe sometimes more than to the rotor magnet.

If you want to see some mu metal, then a little piece of mu metal is inside every audio cassette. It is to shield the magnetic tape from any unwanted magnetic field.

Thank you ayeaye for your input it is very much valued, you have given me a new idea i will do a drawing later today.
