Question about 90 degree separation of magnets.
« on: August 22, 2007, 12:01:54 AM »
This is more of a question then an idea. Has anyone explained why it takes more force to pull two magnets straight apart then whats needed to pull the same two magnets apart by sliding them sideways? I don't know a lot about STORN but I think I read somewhere about a 90 degree rule or something. I admit I haven't given this much thought but I thought I would post it here anyways. So a couple questions I would have are:

Could two magnets pull straight together with more force then whats needed to pull them apart by sliding them apart sideways?

Would sliding a magnet into a repelling field of another magnet take less energy then what is generated by the magnets pushing apart?

Its like gravity in the idea that to pull something up takes lots of energy but to push it across at a 90 degree perpendicular to the ground direction takes relatively no energy besides friction. I have an idea for some experiments that would test this but before I go that far I wanted to see what you thought?

   You have some interesting thoughts here. Think of a car. We move it forward with fair ease. Try and push it up a hill and you have to exert a lot of force. My 40lb neos cannot be pulled apart except by sliding them sideways.

Don't forget saying it's the same is just as much a guess as anything.

Sidewards attraction may also be bigger as face to face. It's likely to depends on the surface area and the strength of the magnets. I think weak big magnets slide with more strength and small NEO's work best face to face.

*edit*

yes, that Kedron link is a good example. I had also seen one using super thin magnets.

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????

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.  ???
