Power from repelling magnets

[ayeaye]

This other drawing here too, with two shielded magnets. The shielding can also be iron, how it is worse is that the edge is wider, and thus there may be more negative attraction. But depending on configuration, i don't know whether it's always true.

What can be an iron shielding, a hammer head? With a proper size and shape hammer maybe. Ah, this reminds me. The core laminations of an old transformer. These can also be easily cut.

The drawing was not the best, so i now refactored it with Inkscape, below. I don't know the exact angle and position, it just shows the principle, it should be tweaked. The principle is that the edges of the mu metals attract, until they overlap each other, then they don't attract any more significantly. Thus one should see a clear acceleration.

Ok, does anyone try to find any theoretical problems with it? I see that there is negative attraction, because a shield attracts to another shield even when overlapped. But this must be much less than the force by which the shields attract from the sides, as this attraction is not shielded at all. In addition because the fixed magnet is tilted, its shield will be further away when the moving magnet moves on. This is the whole principle of shielding. And all that matters is more difference between the positive and negative attraction.

Ok, maybe i should explain too, what is on the drawing, as it may not be clear for everyone. The left magnet there is moving. It moves on a fixed trajectory in the direction of the arrow, like a train moves on the rails. This may be linear, or it may also be like on a large disk, so the movement is close to linear. When moving on the fixed track, all that matters are the components of the forces that are parallel to that track. That is every force is seen as two components, one parallel to the track, either in the direction of the arrow (positive direction), or in the direction opposing it (negative direction). The other component is at the 90 degrees angle from it, in case of a disk the "radial force", that does not affect the movement of the moving magnet at all. The right magnet is fixed in place, and doesn't move, it may be called a "stator".

My another thought is, when using a disk, it may be better to have two stators both working in a complete synchronicity. More than two stators likely doesn't give anything, bout further reducing the radial forces, but this is likely less important. Why, because when the attraction happens at the same time at the opposite sides, then the forces compensate each other, and there is less radial force to the bearing.

Any thoughts about the theory by anyone?

From my experience, my theory is similar to that of Howard Johnson
the shield doesn't just "shield", it diverts the magnetism through the metal.
This comes at the cost of field strength, but we'll set that to the side for now.


What also happens is compression.
It is this compression that operates like a set spring
imagine, that the momentum of the approaching magnet
pushes the button of a mechanical ink pen and retracts it


This causes the field to release the magnetic tension (or build up more) until the interacting
field moves out of range.


What must be understood is the difference between field symmetry and magnetic conservation.
An asymmetrical field is symmetrical in its' asymmetry. or inversely proportionate to the compression.

Yes the shield doesn't block, it likely does that below. There the field lines that without shield did go up, now go to the side.
