Copper is not a very good shielding material. It would most likely just introduce Lenz losses. There is one thing I have wondered about, though. How would a bifilar pancake coil work intead? Is it possible, with the correct spacing and orientation to leverage a gain from one of these?

I'm no expert in these matters. Just thinking "what if?".

Thanks for the info.. I did a google on magnetic shielding and found that a "super conductor" would for the most part shield a magnetic field.. what other super conductor would work best?  I don't know anything about a bifilar panake coil.. I'll have to look into it.

Here is another graphic using gwhy!'s idea of using gaps!

Or gaps in thirds so both ends of the rotor aren't in a gap at the same time..  I think this is the best setup so far.. thanks to gwhy!  I just modified my old graphic.. I would make all three sections use the same number of gates which I couldn't do with my old graphic.

hehe.. I said 12 gates at the top of the thread.. it was 16 gates... anyone know an easy way to draw a 15 point pie.

Thanks,
Jason

I found the easiest way to make a 15 point pie is to use MS Excel..  I'll work on adding the gates and rotor later..

gwhy! thinks it won't work because of repulsion at the entrance of the arrays, but I'm hoping that since only one end of the rotor is going through a gap at a time that the other magnet will push it through... also we can try and modify the entrance to the arrays.. I think overall it is a good design.

I not good enough with graphic to draw this.. the angle for the gates equilateral triangle is 60 degrees (30 degrees from the spoke line)... I want the inner part of the gates to touch each other.. also it has to be scaled so that the outer part of the gates aren't too far apart from the next gate, as gwhy! points out in his latest video that could create a problem... combine the last two graphics and you get the idea.
