I already set it up as I had all the pieces already built to test. And yes there is opposing forces which I think results in cancellation.
The opposing forces are not directly near the activation magnet. It will repel it out when passing, but then after it escapes it pulls it back in from afar. Same with approach. When the rotor magnet is at far distance, the force is against you.
The net sum of helpful forces vs hurtful forces cancels each other out over the entire revolution span.
I am not saying it's a dead-end. It still may be able to be tweaked to become a running unit. I "THINK" as it rotates, the opposite of the rotor magnet starts to align from afar to stifle the effect.
The first thing to try would be to sleeve the rotor magnets in a metal tube so the opposite end gets nullified. Then go from there.

"sleeve the rotor magnets in a metal tube"
Magnetic Shielding uses this principle but it takes two tubes one of mild steel and one of 316 stainless seamless tube.
Its the Magnetic Metallurgy of Iron and Stainless iron. One allows magnetism to go through and the other allows it to go 'along'.
I cant say more than this.

Thanks Merlynn, I may look into that.
Something came about that instilled a renewed interest with the original idea of this thread shown here.
I know I am jumping between projects, but before I get fully vested in the Figuera again I must explore this as I still have all my test jigs out. Last time I got hooked on the Figuera, it took roughly 6 months of heavy building and testing that engulfed my whole work area.
If I get anywhere with it, I will reveal more as I feel something or someone is telling me there is something here right under the surface.

Ray changes / adjusts the set up 4 or 5 times over the course of the
video. This pretty much wrecks / invalidates any data we could have / might
have been able to get.
Camera angles are bad at best.
At 5 min. 55 sec. It looks like attraction in and repulsion out, but who can say
with any certainty ? He does no demonstrate the "balance" of the wand.
Starting at 6 min. he could easily have demonstrated the "attraction", but did not.
There is to my knowledge, no reason for which his device would net other than, a zero gain.
Did any one notice how the nails are positioned? It maybe nothing but why use masonry nails ? 10 guage and his finder is 8 guage? And his finder has a magnet on it , and is some what balanced. If you do his experiment do it as he shows.we will other wise have all sorts of hypothesis when finished.
Ok so the experimentation continues.. This project persuaded me to upgrade my 3d printer to one that can print 500mm / sec. Wow this new printer kicks ass..
So I am working on what I demonstrated in the first video of this thread. I demonstrated in Cadmans thread how we do have a sticky spot, BUT that sticky spot should adhere to Newton's 3rd law. So the sticky spot should be equal to the force that pulled it in. Which means it should not be much of a hinderance..
I am now working with Ferrite Rings to reduce eddy currents. Here is a pic of some of the things I have tried. Right now I am concentrating on what arrangement and materials give me the strongest magnetic field in the ferrite. The full rings did OK, but I found another way with ferrite that definitely increases the magnetic fields, which I am printing now.
In case people don't understand what I am doing here, there is a center piece with 2 arc magnets, N/S. That stays stationary.
Then a rotor spins with ferrite rings that pass the magnets Ultra Close.. So the rings get magnetized then flip polarity as they pass the 2 magnets.
As I pointed out in Cadmans thread, when ferromagnetic material passes 2 poles like this, it is most attracted to the sticky spot right between the 2 magnets. So the ferrite rings or studs need to be magnetized as strong as I can.
Once I am satisfied, I will try with the gears. At the moment, there is no need to print gears till I find a good arrangement.
When the stator magnets are arranged South / North like the image below, it creates a big sticky spot at TDC. If ferromagnetic material is aligned with North, it turns North. North is attracted to South and South is attracted to North. So the temporary magnet just want's to get between the 2 poles and stick.
View this video I posted in another thread to see what I mean.
Now if we arrange it a bit differently, we can eliminate that sticky spot and still reverse magnetic domains of the temporary magnet.
If we shift the stator's polarity divide by 90 degrees the magnetic responses change. Like this:
Now when the temporary magnet is over the first magnet, it is South. Now the mid section is North and South at the same time, so the temporary magnet is both Attracted and Repelled to the mid section, thus eliminating most of the sticky spot. Same thing with the exit from the mid-section to the next single polarity.

Thanks Jim. That is what Butch Lafonte was doing 15 years ago. The problem is 1. set the device up for potential work out. 2. release that potential. 3. use some of that work to reset it to repeat. But that cannot be done if the work out is not a least 250% or more from all of my experiments.
That is what my last drawing shows. I am in the process of embodying that drawing in the next few days so I can measure the work out and in to see if it can be OU. Butch Lafonte never did any measurements but he inspired me to measure and experiment.

But Jim the good thing is you are trying when many just post their theories.

Jim most people do not believe that permanent magnets can do work but Howard Johnson made and patented a PM motor. I have only one friend that encourages me. And none of my family believes in what I work hard on. There is an extreme shortage of curiosity.
Keep at it. It took me 15 years to validate Butch Lafonte's ideas.
