Question about 90 degree separation of magnets.

[Honk]

The magnets should not touch each other when sliding. To much friction loss.
Imagine a rig that lets them attract together but it stops at a gap of 0.004".
Then let the rig pull them apart sideways with no friction loss.
Will there be any excess energy to harvest?

Will there be any excess energy to harvest?

yes, beyond any doubt but you will find it very hard to engineer a low friction wheel that moves in a square. You won't get anything out with just this concept.

What you can do is move the magnet into a zone where it's attracted again. Then you get a Minato wheel kind of contraption. But no real straight approach or real sliding sidewards.

I think it would be interesting to investigate manipulating the sliding with a pulse from a coil.

You may be able to generate enhanced sliding. The other (pushing) pole of the magnet is pretty close.

So you could slide it from the magnet over a coil. Or you could help push the magnet sidewards.

If you would build 2 of those sliders you can push and pull with the same pulse.

The thing would be pushing against and pulling at the side of the magnet so the sliding pulse also needs 2 poles I think.

I still don't see magnets make 90 degree corners at reasonable speed.

wait, maybe I do see how..

Make one magnet resonate (swing) up and down at the end of a strip make a cut in the strip and put another strip in the cut and fix that to a standing beam.

Then it should flap up and down while flapping from left to right right? put a magnet over it and if sliding can be exploited you may be able to show it with such construction.

I personally think rotating the magnet is a much better concept.

Wait, I'm lost. So which would take less work to do? Pulling them face to face straight apart or to pull them apart by sliding them sideways?

I think your saying that the work generated by two magnets attracting face to face is greater then the work needed to slide them apart? If that is the case I don't think harnessing that would be too much of a problem with a design I have. If its the other way around or equeal then I would have to work on it a little.
