Hi everyone,
I'm new to this forum and this is my first post. I was thinking about magnetization reversal concept. If we can reverse magnet polarization using little energy then we can achieve overunity (see it like we control direction of high energy using low energy).
There's ongoing work on this, especially directed towards fast hard disk access, for example recent work about reversal using light: http://en.wikipedia.org/wiki/Magnetization_reversal_by_circularly_polarized_light
My idea is about reversing magnetization of a magnet while retaining much of the energy used in this process. Everything is on this picture:
You will have a problem of broken cable connections to solve.
The center coils move side to side and will break the cable connections.

I think I can lay out wires along vertical bar to the lowest non movable axle. There, wires movement is minimal.
Make the magnets spin, not the coil...
If you spin the coil, you will need a commutator, like in a DC Motor.
But if you make the magnets spin instead of the coil then you don't
need to worry about the wire stress or the commutator...
Reversing the magnetic field will help you convert mechanical energy
into electrical energy, but its not overunity...

Thanks for your replies. I realize that moving magnet is better than moving coil, but then I would end up with only one permanent magnet so magnetic force would be weaker.
If I want to stay with 2 coils like in nievesoliveras's idea then I would need to magnetize two magnets simultaneously. This will lead to even more losses and it needs more power, so moving coil (around center magnet) and two permanent surrounding magnets is IMHO the best option (3 magnets + 1 coil). In this case both permanent magnets contribute to center magnet motion. There's also possibility to make them bigger and stronger to increase mechanical force even more.
Wires could be placed along vertical bar. Horizontal movement of that bar on it's bottom end should be minimal. Nevertheless current flows only at the endpoints, near permanent magnets. This fact could also simplify whole design.
One thing I forgot to add about that concept: as coil moves in the magnetic field there's always EMF in that coil (because of electromagnetic induction). This EMF could also be used as additional source of energy.
Clarification:
Each coil will be without a magnet inside it. The pulse of one will be negative and the pulse of the other positive.
When the negative side of the magnet go to its coil side the coil will pulse a negative magnetism and viceversa.
It can be achieved by cheching with a magnet and changing the coil position. I mean if you see that the coil is attracted to the center magnet instead of repelling, turn the coil so the other side looks to the magnet.
The coil has a positive and a negative side when pulsed.

This is something different from my idea. I'd try to explain in other words: there is center magnet and two coils wound around it. Coils are used to magnetize magnet and after the current-pulse, it performs work by itself because it remains in magnetized state (it is called magnetic remanence of ferromagnets). So there's constant work without constant supply of energy (opposite to solenoid case where constant work implies constant supply of energy). In your pulsed solenoid case, there's only little momental work (because the pulse) and after the pulse, magnet is moving only because of its momentum. This is completely different.
My idea is about using magnet to perform work without any energy, but magnet must be inverted to ensure continuous work. So there's need for additional energy to perform magnet polarization reversal. Strong current pulse in the coil produces momental magnetic field strong enough to magnetize magnet in particular direction. After the pulse, magnet remains magnetized and constantly repel and attract to both surrounding magnets and in that phase there's no current flowing into the coils. Two coils are used to work as 1:1 transformer, which retains pulse energy for later use. Pulse in one coils gives immediate output on other coil like in transformer. So if there would be no losses then we could invert magnet polarization without any energy.
I will Just watch and learn.
