Magnets, motion and measurement

I don't think of "Near Strong / Far weak" as being exceptionally
problematic.

That is an excellent writeup Floor. I missed that somehow.
I have used variable levers so I have to see how that applies.

Please find below the attached   "Magnetic force shield repulsion" PDF file.

This is a design all ready presented on this topic ... but those drawings were as functioning
in a magnetic attraction mode.

Looks great Floor but how do you get the middle magnet pushed back in
so the cycle can be repeated? It could be easily inserted from the viewer
when both mags are matched rather than inserting from the end as the
drawing would suggest. And then how do you get the 3rd magnet on the right
to go back so it will repel because it is red to red and black to black..

Also remember closer stronger repel and further weaker repel so the
drawing is correct but that distance is likely not as realistic as it is to the eye.

I was grand parenting for a week and out of action so have to catch up.

Floor I did get your blocking magnets to work when I made it right and it does
slide in and out easily if the sliding magnet goes along the line of the joint between
the two magnets of opposite poles.

Now I need to measure the forces to move vs the output.

In the past I have had several OU devices but to do the feedback and switching
to make it self run it needs about 300% OU. I was never able to get more than
about 250% and Like you I used weights to get accurate measurements.

You sure have an eye for magnets.
