Split iron parts apart with magnets.

[Low-Q]

I guess you have seen that if you have two metal plates, which are placed upon each other, and approaches a magnet, the plates will separate from each other - because they are now magnets with the same pole at the same side of each other.

If the magnet are fixed at a constant distance to the plates, and you try to squeeze those plates together, the attraction forces to the magnet will weaken. The plates are most attracted to the magnets when they are separated with a given distance from each other. At this point there are no longer any repelling forces between the plates.

So I did a simulation in FEMM. That shows a magnet with two small metal pieces above it. This magnet have the poles aligned vertically. When the metal pieces are 0.1mm apart, the attraction between the magnet and the metal pieces are 43N. The repelling force between the metal pieces are about 13.6N. When the pieces are 1mm apart, the attraction to the magnet are increased to 47.5N, and the repelling force between the pieces are reduced to 7.7N.

The average attraction force to the magnet during separation of the metal pieces are 45,4N, with a total difference of 4.5N
The average repelling force between the metal pieces during separation are 10.2N, with a total difference of 5.9N

I am skeptical to magnet motors, but are these numbers anything to twist your minds about?

I did some work with real world testing of this principal, and everything shows that after the plates separate, it is now harder to remove the magnet, as you have shown.

The magnet must be removed to a greater distance to place the metal pieces back together without work, to remove the magnet to a greater distance at the higher attraction will take the remainder of the work you have gained.

I found placing another magnet at the other end of the steel, in repel to the activating magnet, will allow the iron to connect back again and invert the problem. So in the end it did show some gain using the inverting method.

I also advanced this to using two magnets in a tube repelling each other, then placed iron along the sides of the tube to allow the magnets to lose much of their repelling field. This showed the most gain.

Have you tried to work further with your last procedure? What was the outcome?

Thanks! I will take my time to read and watch
