Magnet force shield

Looking at Floor's fig 4. The 2 mags on the right can be replaced by one because you want
as small a distance between the 2 repelling mags on the left. Then that single magnet can be moved to the right and then repelling magnets can do work. But they need to stay in place
and at equal distance until the single magnet is moved to the right. Then after work is done
they need to come back together so that more work can be done. I call that move the reset.
In order to do the reset those magnets need to be at equal distance from the single magnet.
If at equal distance the single magnet can be moved in between the two repelling magnets
and then the repelling magnets can be pushed together.  Then the reset is complete and
all setup for another push apart and work cycle. 

With a single magnet so the repelling magnets can get closer stronger
I believe this setup will work and I will test it and report back.
This is exactly what I have tried to achieve in many ways and failed to do
when work is taken out because the balance becomes unbalanced.

To test simply take 3 equal magnets and arrange 2 to repel with the other
between to see that they can stay there if held equally then remove the
middle magnet and see how far it moves the repelling magnets. That will
be pretty far but remember that the further away the less force meaning
where it stops there is no practical force.

But the thing that has caught me many times is distance. Lets say the magnets
give 1/4 inch of work but the magnet move distance is 1 inch. That is a  lot to
compensate for. It will probably be OU but In my failed cases it take about 200%
efficiency to move that magnet out and back to complete the cycle.

My quick tests show that this will work but there are 3 distances that might prevent
a self runner. 1. move single magnet away 2. release the repel mags to do work.
3. move the single magnet back 4. move the repel magnets back close to they
can repeat the cycle....

This assumes that the repelling magnets are mechanically limited to equal distance
travel with something via something like a vise grip arrangement.

Now I have to arrange to test the work in and out in the sequence above...
The repelling force will be OU but I doubt that there is enough extra to do the reset.

I did something like this but I can't believe I overlooked sliding the single magnet
to the side.

In the drawing (Magnet force shield 5. png) a single inner magnet (of the same type as the outer magnets), will be over powered
by the outer magnets, at close range. 

I did the (Magnet force shield 6 and 7 png) drawings to make the concept of that over powering clear.

A magnet of greater strength is needed for the inner magnet. 
          this might suffice
two magnets glued edge to edge (1 magnet thickness, but 2 magnets wide).
like poles (on the faces) on the same side
these will be repelling n to n and s to s at the edge.

easier than acquiring a custom magnet !

Note .... the strength of these cheap ceramic magnets can vary greatly from one to the next !
Because of this I have a large selection of them (to match them in sets ?).

  please find the attached ...  2 force explanation drawings.  (Magnet force shield 8 and 9 png)
note.... different design not directly related to the current discussion.

A small pdf file (works as a flip book) of the rack and gear action.

Shrink the pages until they just fit the screen, then page through them.

I dug out an old miniature rack and pinion gear set from my parts stash.  I need to replicate / cast in plastic the pinion gear and two copies of the rack gear.  I think I'll make several copies while I'm at it.
