Work from 2 magnets > 19% output 2

[Low-Q]

So here are the results that I calculated to have a gain of about 12% excess output over input.
I tried to make it easy with all steps including the rotation move to be .05"
You can see from the negative number in the data, that near the end of the sequence the magnets pull together.

The magnets at their zero spacing have about .03" gap in all the tests.

I also added a short animation of the entire sequence.

What is the torque readings you got here? It looks like you have only calculated the linear force between the magnets.


EDIT: Or is the Force readings actually torque? in Pic2? If it is, it require about 7.32 Joule to turn the magnet 90 degrees. You get 0.11 Joule in repulsion in Pic3...()

The torque is the force at a radius of .5093 from the center pivot point.
At this distance, a 90 degree rotation causes a linear movement of .800" inch.

This keeps the travel distance and step size equal over all tests.
I simply added all the forces in each set and divided by the number of steps to get the average step force for each set.
You need to find the average so the zero readings are included over the full distance traveled.

OK. I don't think I understood that
What software are you using to measure forces in 3D?

The measurements in the pictures were made from real magnets using a digital scale and CNC machines to apply the forces.
It's intent was to verify the forces indicated in software using "Maxwell 3D"

It appears that both software and the real tests produced similar curves for each test.
The software used N35 magnets and the real tests used N42 and might explain some of the difference in results.

I have a larger set of magnets (1/8 x 1.00 x 2.00) that are much stronger and it might be interesting to test in the same fashion to see if the results are similar.
These larger magnets should have forces more suited to my scales range and the variation in shape should change the result for better or worse.

I also have another set that are very strong (.50 x 1.00 x 2.00) that could be tested in a similar test or with the parallel orientation as in floor's tests.

Because these are all neodymium magnets there is likely no domain shifting within the magnets and the only theory I might have for gain in energy would be that the field itself might be partially assisting with the alignment.
