6 magnets in the track..

See attached jpg below

Approximate dimensions.

JPG attached below.

But with 6 magnet track length.

I will adjust / trial and error the dimensions.

A design which is of this type will be suitable only for
very permanent magnets like neodymium magnets
                or..
if some other magnet compositions are found, which are
highly resistant to demagnetization.
... ... ... ... ... ... ... ...
I'm dialing this test in.
As should be expected.  A change in one aspect of the
interactions affects other interactions.
It's a trial and error process.

The device, when the track is 6 magnets long, has a lull in
the output force near the center of the output stroke.

The force to distance curve of the output magnet's travel
is different at the two extremes of  that travel.

It is not a simple force to distance curve.

As Norman 6538 points out...
In order for any of these designs to O.U. cascade,
output must exceed the input by > 2 x.

As an aside, but very related...

This magnet arrangement is very nice.

3 minute video (previously linked to)

3 magnets in the track instead of 6.

I misstate (was expecting)  in the video that there are sticky spots
when the sliding magnet is very near the track magnets.
                   but there are
No sticky spots, except when the sliding magnet snags
on one of the track magnet edges) in the 3 magnet track

There is Consistently, a force in the desired travel direction
           @
https://www.dailymotion.com/video/x80z9wr   ... 3 magnet track

                          however

There are sticky spots in the 6 magnet track,
          at the 2nd 3rd and 4th junctions.
There is no sticky spot at either the 1st or the 5th magnet junctions.
           @

This all makes good sense.

It looks as though, when using this particular design and magnets, I may
need to limit the track length to 3 or 4 or 5 magnets ?

We will see / trial and error.

Point ?
To be able to freely insert / extract the output magnet from over the track ( near the ends),
while maximizing work done in the output magnet's travel over the track.
