The only reliable way to overcome the shield problem is connect two cifta units
back to back, the way they are now.
Then rigidly connect shields.

When you stack several small magnets together, the polarity of them getting rearranged,
and out of several small magnets appears one big magnet, divided in the middle with
north/south polarity.

Which citfta unit?
Last I looked,  he had presented 3 variatiions.

I put together two repelling magnets, opposing each other.
I inserted a similar magnet between them.
It was attracted to one magnet, and  simultaneously repelled by another.
I tried pulling it out - the force of pulling out is considerable, so high, that I couldn't pull with my fingers.
Attaching the image - couldn't place camera at the different angle, since one hand was holding the setup.

This is not one of the designs which I had presented. Apparently, it is a misinterpretation one of the designs I presented.  Where that misinterpretation got started ?  Lumen ? Tinman ? and apparently by you as well ?  I don't much care at this point.

Although I have since, addressed it on several accounts, and I'll say it again, for those whats hearing impaired.  Not a design I had presented.

But here is the solution to it's "problems" if you are so inclined as to grok it.

Next......

Will the shielding magnets, prevent the repelling of the
output magnets when it is between them ?

Will the shielding magnets be easilly removed from or
installed into between the output magnets ?

The Newton's magnets topic is intended to address a very narrow vein and a specific line of inquiry.
Thank you for being the one to, move this over to another topic.   The Newton's magnets topic
was not the right place for this discussion.  Definitely  related, and some what relevant, but still off topic.

I see that you had already arrived at a solution to that "problem".

Have I correctly understood your concept / observation ?
   and
Does the above drawing (Lumen's innovation 2.png),  adequately / correctly, express / illustrate
a version of your suggested solution ?

Note ..... There are some other solutions.  Yours, I like !

Good eye, nice solution.

In your diagram I don't quite understand the fine-tuning part, but the rest should
work IMHO.
Forces on each shield should be neutralizing each other, since they act in the opposite directions in A and B.
I would make both shields coaxial rather than parallel to illuminate unnecessary
rotating moments.

Hi Telecom,

Maybe this will help you understand better what Floor has been saying.

Hi Carroll,
you have a great building skills!
On 3:00 and on, I don't see any indication that this shield actually reducing the repelling force.
I tried this myself on a more crude setup, and also haven't noticed this.
Nevertheless, this is a great demonstration video.
Regards.

TO ALL READERS

          Just for clarity...

               Pleased as CITFTA has been with his builds / results and I would agree that they are pretty skilfully built.
               A nice innovation in the use of the glued down toothed belt as a rack gear and so on........
                            But once again.
              NOT A SINGLE ONE of the 3 videos CITFTA has present, is of a design which I had presented.

              Each video has some similarity to one of the designs, but IS NOT ONE OF THOSE DESIGNS.
             
              Not a single one of them is a correct representation of ANY of the designs I had presented.
                   
            What do you think the odds are of 3 misinterpretations in a row, like that.
           
            Bad run of luck for CITFTA I'd guess.  I agree with CITFTA's statement that he should maybe give
            his self a break from the builds for now.

                   best wishes

Have you watched the videos above ?

I finally watched the videos, but have a hard time understanding how the tuning magnet works.
Can you please provide a diagram of the setup + forces.
It seems, that when your close field interaction starts to yield no efforts, far field interaction becomes a problem.

Study up on magnets.

Aren't you here to share your knowledge with us, layman people?
Tired of your arrogance.
