Power from repelling magnets

[ayeaye]

I think it is rude to keep insisting the name of the thread is wrong when you didn't start the thread.

I did *not* say that the name of the thread is wrong, this is what i didn't say. I really only wanted to say that this thread now appears to be only about attracting magnets, that's all that i wanted to say. And not because it's wrong, but because of where it went.

Improved my spring scales image again, now the background is transparent. This image is public domain.

We can harness the power of magnetism using either force.
Repulsion / Attraction are basically inverted


Invert your arc-path and use the other side of the magnet
Attraction arc is towards the field
Repulsion the arc is away from the field


In the attraction sense, it most resembles the gravitational assist
you arc around the field, accelerating, and leave with a higher velocity.


In the repulsion sense, the interaction takes place at the peak of the arc
as you approach the magnet, and are accelerated away along the 2nd 1/2 of the arc


It's all about the angles and relative motion
And when you get it, you won't worry about the negligible friction

You approach the magnet (by a pole of another magnet or by an iron object) where the attraction is greater, you accelerate, then you leave where the attraction is less, decelerate, but the acceleration is greater than the deceleration, so you leave with a higher velocity. And this requires asymmetry of the field, it is impossible with a symmetric field, as then the deceleration is always equal to acceleration, when the magnet doesn't move that is.

Friction matters, one can gain speed, but for continuous rotation this speed has to be enough to approach the magnet again, due to friction the movement mostly stops right after leaving the field of the magnet.

And how to saw off a corner of a rectangular magnet? To make it asymmetrical? Neodymium magnet is fragile, it will crumble. You tried?

This will not make it more asymmetric i think. This asymmetry i think comes from the properties of the atoms, it is the same with any shape.
