O.U. Magnet force shielding 1

[Floor]

I've always had more optimism than successes, but learned just as much
from the unsuccessful as from the successful.

Presenting things on the fly, optimism and all, may make it seem as though
my methods are / have been unscientific, but this is never so in the end. 

I'm not trying to disappoint anyone.   People used to say "don't believe every thing
that your read", but it seems like this has been forgotten in the internet age.  A healthy
mix of optimism and skepticism (not cynicism) is needed.

Having this design in my pocket so to speak, for some time (years) now, has given me
reason to continue exploring other designs and variations. 

Don't get me wrong,
It's not that I have hidden it (at all).  I simply didn't shove it down peoples throats.
See for your self, and so on has been / still is my course.

Arriving at a near to zero input work against magnetic forces
while inserting and removing the shunting / shielding magnets
is the primary goal.

Then arriving at the optimal output magnet travel distance.

Note.
The shield magnets will demagnetize each other eventually.

O.U. becomes what ?

From the movie Harold and Maud.....

"Dreyfus once wrote from Devil's Island that he would see the most glorious birds."
           (In the distance / from his cell window ?)

"Many years later in Brittany he realized they had   only   been sea gulls... For me they
will always be - glorious birds. "

Floor I need a clarification on the mag polarities for the magnet that moves in between the 2 attracting or repelling magnets.

Using  2 mags, if you lay to mags down side by site with opposite polarities up they will pull together and stick. Is that the correct polarity of those mags?

When I test the two mags with opposite polarities up I see an imbalance between the intended balanced attraction and repelling  of those mags as they approach (along the line where they are joined) the stator magnet.
Thus unable to achieve a balance to make this work nor get measurements.

Leedskalnin has said that north or south magnets push more than south which means the forces are not equal.

a partial quote only

I tried the stack setup before and had no luck so this time I am using the 4 magnet
setup in repel mode  "the Magnet Force shielding 2  design"

Norman

When  using the     two magnet stacks setup,      this is the Magnet Force shielding 1 design,
NOT the the Magnet Force shielding 2  design (as you stated above). 
Magnet force shielding 1, is also the title of this topic.

Here is one of CITFTA'S  videos (short 4 minutes)
     @
https://www.youtube.com/watch?v=wHHVrQRby9A&t=174s

              NOTE...
CITFTA's  magnet POLARITY MATCHING is well and correctly labeled in that video,
but that may be just about the the only thing that IS correct in the video.

Leedskalnin is INCORRECT, in general, N to N or S to S repelling force is the same,
unless there is some defect or inconsistency in the magnets used.

PS

If CIFTA had positioned his magnets as all N faces, the POLARITY MATCHING
would be the same.

ie.
1. Each pole at the top of a magnet stack is repelling the pole on the top of the
other magnet stack.

2. Each pole at the bottom of a magnet stack is repelling the pole on the bottom
of the other magnet stack.
... ... ... ... ... ... ... ... ... ... ...
3. Each pole at the TOP of a magnet stack has the opposite force of the TOP of other
magnet stack in relationship to the shield magnet (if the one repels then the other attracts).

4. Each pole at the BOTTOM of a magnet stack has the opposite force of the BOTTOM of other
magnet stack in relationship to the shield magnet (if the one repels then the other attracts).

There is a lot of force present (see video).

Rigid sliding tracks are a must.
If you don't have them, I don't recommend trying the set up.

PS
  I should add... 
    CITFTA, my for gratitude for the time and effort spent and for the quality of your
builds.
