Magnetic-mechanical counterforced PPM

[Low-Q]

The subject isn't telling much about this idea, but I have an idea that is based on a system which is working with forces that is partially magnetic and partially mechanical.

In the picture below I have made a drawing with my kids pencils... Anyway, let me explain the idea:

In the drawing to the left you can see that the iron/PVC parts are shaped so they are facing a gradually increasing counterforce when entering the two spring loaded ballbearings. In this position a similar iron/PVC-part is gradually attracted to the magnetic gap with the same force. So the result is that no force is required to push the iron/PVC parts.

In the drawing to the right, the iron/PVC parts has passed the most attracting/repulsive part. The idea is that the iron part is now almost no longer attracted to the magnet, but the force in the spring loaded ballbearings are still present. So now the iron/PVC part can be forced forward.

I must have a mechanical repelling system (The spring loaded ballbearings) so the iron isn't affected by a possible magnetism in that particular part of the system.

I hopefuly are able to build a device that is based on this system.

What do you think? Where is the possible flaw of the system? I am not posting this to fool anyone, because I honestly do not know where the possible break is in the system - except friction.

NB! Only look at the forces. Friction is not interesting to discuss here - even if it is interesting do discuss :-))

equal force means equilibrium, no movement,

you need one force larger, but that would mean it would stop itself also


if the force of the springs is enough to get it out of the magnetic field (making one side stronger), the magnet won't be strong enough to push the spring back into position

likewise, if the magnet is powerful enough to set the spring all the way, the spring will not be able to pull it away from the magnet

if you have the same forces on a lever, it balances and doesn't move,

i think thats how it would work out, but thats just my opinion

i like how your redirecting the force of the spring for almost "lateral" movement

I thought of it later after I posted the drawings, that if the iron is possible to be removed from the magnet easier than the force that is draging it in, the iron would probably run by itself... I know that does not work out...

I have to think a bit more again...
