O.U. Magnet force shielding 1
« on: May 28, 2021, 08:46:34 PM »
This design goes back to 2017.
Some folks are well aware of it, since that time.
Others missed out on it.

Out put
1.
740 g at 1/2 inch
700 g at 9/16
650 g at 5/8
600 g at 5/8
550 g at 11/16
500 g at 3/4
450 g at 13/16
400 g at 7/8
350 g at 31/32
300 g at 1 1/16
250 g at 1 3/16
200 g at 1 5/16
150 g at 1 5/8
100 g at 1 3/4
50 g at 2 9/16

input
2.
Shield out < 5 grams by 2 inches
input
3.
Shield in < 5 grams by 2 inches

out put
4.
Return of out put magnets to starting position is also an out put /
a net gain in energy as mechanical work.

As a very conservative set of calculations, this is a 20 input to 600 out put ratio
or 30 X unity.

SO LETS TEAR THIS THING APART NOW.

Out put
1.
740 g at 1/2 inch
700 g at 9/16
650 g at 5/8
600 g at 5/8
550 g at 11/16
500 g at 3/4
450 g at 13/16
400 g at 7/8
350 g at 31/32
300 g at 1 1/16
250 g at 1 3/16
200 g at 1 5/16
150 g at 1 5/8
100 g at 1 3/4
50 g at 2 9/16      =  412 work units
... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ...
The last quarter inch of travel, when the shield is in, is in attraction.
An additional 1/4 inch would be available, except that the magnet holding
fixture interferes.
             unaccounted for
With out the thickness of the shield magnet fixture (in the way)
OUTPUT travel (while the shield is in) would have an additional 1/4 inch of
OUTPUT travel (while the shield is in) and (while force is at or near maximum).
                  also
             unaccounted for
With out the thickness of the shield magnet fixture (in the way), the main
output (while the shield is out) would have an additional 1/4 inch of OUT PUT
travel (while at or near to the maximum force is available).
... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ...
When the shielding magnet is positioned / optimized (up and down) for
        VERY NEAR TO ZERO INPUT AGAINST  MAGNETIC FORCE
during insertion and / or removal...   

There is a repulsion force present (at the distal range of travel) while the shield
magnet is in place.  This force gives rise to the need for an INPUT in order to return
the out put magnet to its start position.
              but...
That force reverses direction (changes to attraction) as the OUTPUT magnet becomes
near to the shield magnet.
... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ...
When the device is operated such that the output travel range is limited to around 5/8
of an inch, output occurs when the shield is removed and then again when the
shield is restored.

With modification of the output magnet holding fixture, the range of travel would
become, 7/8 inch (5/8 + 1/4).

With first an average force of > 607 grams over the 7/8 inch travel, then
an average force of around > 150 grams over 1/2 inch of travel, while an
additional 3/8 inch of travel is at neutral force.

In this mode of operation, and when considering that both shield installation
and  removal can actually approach zero work against magnetic forces, the device
becomes, in this context almost pure O.U..

Given that an ideal operation is not achievable, still I think
a ratio of somewhere from 10 to 15  to 1 is realistic (Output to input).

The magnet stacks, which I have ON MY BENCH AT PRESENT
(A and B illustrated below), are not well matched.   

One of the sets of magnets is stronger than the other.
This was not intentional nor by design, but by chance.

If the magnets in those stacks (on my bench) were more nearly
identical in terms of their force magnitudes, their interactions
would be significantly different.

On my bench, the shield magnet is not vertically centered in
relationship to the magnet stacks. Instead (in order to arrive at
zero force insertion / removal) the shield magnet has been shifted
down ward from center.

If the stacks were well matched, zero force to insert / remove the
shield magnet, would be made possible when the shield magnet
is centered vertically in relationship to the two stacks of magnets?  (? is an edit)

Under those conditions, we would get a better input to output
ratio, through the four step interactions (longer / better output
travel distances)  ?

Output 1.
an average force of > 607 grams over the 7/8 inch travel (repelling).

7/8 inch = 0.875 inch
0.875 x 607 g = 531.125 work units

 then

Output 2.
an average force of around > 150 grams over 1/2 inch of travel (attracting),
while an additional 3/8 inch of travel is input (against zero magnetic force).

0.5 inch x 150 g = 75 work units
... ... ... ... ... ... .,. ...

531.125 + 75 = 606.125 total work units out by magnetic force.

At nearly zero input against magnetic force  (we will give it <5 grams)

 edited below (from 1.75 inches to 1.875 inches)

1.875 inch shield travel x 2 (insertion then removal) = 3.75
3.75 inches x 5 g = 18.75 work units input

18.75 in to 606.125 out ratio.

You can see what the output action in this design is like,
near the end of this video  https://www.dailymotion.com/video/x81pgdx
@ the 16 minute mark.

Although that video is of the Magnet Force shielding 2  design, the actions
are the same as in the Magnet Force shielding 1 design.

Measured out, the Magnet Force shielding 1 design outputs around
34 times the input.  The Magnet Force Shield design 2 is not going to
perform as well.  It might even come out at unity ?  I don't know.
I'm still not, at this time, set up to do those measurements to my satisfaction.

I occasionally put this design (Magnet force shielding 1) on the bench
(again yesterday), just to check my own sanity  :)
      Its good.

Floor I appreciate your continued work. I have been too occupied to do this but I have a few comments. 1st mount your camera so it does not move around. I made a U shape with groves in the sides of the U that my camera slips right into to hold it. Then I mounted this on a pedestal that I can move around to get a good view or change views.

2nd I put your grams and distance into a spread sheet calculating the grams times the distance moved for each increment of work out and then work in vs out got OU 39 which is very good...congratulations. I almost always use spread sheets to eliminate calculator keying errors.

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"
My test is gluing right now so I won't have any results till this evening or tomorrow.

The other thing is you keep changing topic and threads and I don't catch the new threads all the time. but the unread overunity feature helps.

@ Norman6538

Howdy

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

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).
https://www.youtube.com/watch?v=wHHVrQRby9A&t=174s
 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.   

  best wishes
