Just as a start off point here I am going to say that eventually our world will become less habitable for humanity if new branches of technology are not explored.
Now, alot of people out there say oh well the scientists will figure it out. Science progresses no matter what, yadda yadda yadda. But what do scientists really do? My answer? They make things better, they live to improve, to make things work smoother, faster, and more efficiently. Detail men to the core they always progress because there is an infinite amount of details to improve upon. And that to me, is what a scientist really is.
On the other hand. We have people i will label as inventors for now. and they are the polar opposites of scientists, inventors look at the big picture they play with theory's and idea's waiting for the big moment where they will have discovered something nobody else has. Simple or Complex while scientists work towards the top of the proverbial tree inventors work down creating new branches while scientists concentrate on making every leaf perfect. Both are required to sustain both continued life and expansion.
Now take that picture of the tree and compare it to our world. Everyday people on this planet become closer together and more intimate with each other. We have discovered much about our planet and still continue to do so. Everything from energy sources to weather patterns, to genetics and evolution. The leaves on this tree are still far from finished, but could things like global warming, fossil fuels running out, genetic destabilization, ect... be telling us its time to find that new branch? the new science? Or we can be so bold as to say the new tree. Of course I'm sure everyone has their own opinion about this, and we'd love to hear from you!
Now, in my scenario which involves the interactions magnets have with electricity. I believe, that the answer is simpler than people think. In fact i believe that it involves just looking at the problem from a different perspective, which may be harder to do than you realize.
Magnets and Electricity i believe are a unique pair in that their interactions are so closely related to each other via that Magnets(with another acting force) can induce electrical current, while on the other hand electricity can can make a material(iron) magnetic either permanently or temporarily.
This is not the only place where interactions of this nature occur in the world, however it is related very strongly to a problem that is quickly overshadowing the world. Power, will we be able to create long term plausible energy source? What happens if we can't? Will solar, wind, water, nuclear, ect... be enough?
To get into more detail, say we have a magnet. This magnet has no outside force being exerted on it. Say for example there is also a wire perpendicular to the magnet. In this wire are many many electrons each with the property's of being its own little magnet. The original magnet exerts a force on these electrons which pulls them in two directions, much like a car making a tight turn. You accelerate to the turn and then must slow down to actually turn the car onto the next road. Same idea. And that is the end of the interaction of the magnet and the electron, because there is no outside force moving the magnet.
In a generator which uses say a gasoline engine to turn a shaft which in turn rotates a magnet inside a coil of wire and produce electrical current. The magnet "holds" the electrons and as it rotates around in a circle the electrons are also moved around the coil thus creating the electrical current. And basically the energy exerted in creating the force that rotates the magnet equals the energy being output as an electrical current.
Now the important thing to take out of all of this is that the stationary magnet does effect the electron when either the magnet or the electron are moving. So, we know that to complete the relationship of magnet to electrical current we need a third outside force. Now you should say, that third force must be constantly applied to be useful and that would imply a constant state of equilibrium. This is where our thinking diverges.
But not quite. I do agree that you need to have that constant third force be applied to either the magnet or the electron in order to have an effect, however if per say the magnet is not moving a you use an outside force to start an electrical current"generator" Remember, when a magnet is positioned next to an electron it forces the electron to move in two directions both forward and left or right. If you position two or magnets in such a way as to cancel out the side to side force while keeping the forward acceleration the electron has a net gain of velocity.
Keep that in mind and now remember that electrical current has the power to create magnets themselves, and in the case of a permanent magnet, it can increase its power (force, whatever)
That would create a loop of a constant rate of acceleration. (maybe) Which then could be used to both replace the generator as the third force and do whatever.
I could be completely wrong.
But i enjoyed writing this post.

The trouble is that if you have a wire going through a ring magnet to accelerate the current by pushing (repelling) it, it has to reach the ring magnet in the first place which is repelling it, so what it gains as it leaves the ring magnet behind, it will have already lost reaching the ring magnet in the first place. It is a bit like saying that if water flows down hill it will go faster and so have more energy but you have to get it uphill first, so loose energy.
Particle accelerators use this idea, with the current for the electromagnet turned on as they pass so only pushing them ever faster on every circuit. Unfortunately you cannot use this on a continuous current and it takes more energy than it makes to use an electromagnet in this fashion.
But keep coming up with ideas. One may be the one that makes a difference to the world one day.

I wasn't really thinking along terms of ring magnets. I would imagine something more along the lines of say a a large coil with bar magnets placed perpendicular to the wire in a circular fashion both inside the coil and outside. I dunno if thats easier to visualize, maybe i will try and draw it.

Not the right wording but you basically have to use the magnet to push the current through the wire, so the magnets have to be in a position to do so.

Well i agree that magnet has to be moving in order to create a current.
Here i go with another probably wrong explanation
Because the effect the magnet has on the electrons travel depending on whether the north or south pole is facing the wire is at first an accelerating force towards the magnet with a speed retarding curve either toward or away from the magnet, again depending on which pole is facing the wire.
If one can essentially nullify the energy loss the electron faces by making that turn either towards or away from the magnet you have a small net gain of energy. Perhaps that is too bold a statement, it makes sense to me.
And i do believe, although i may not understand that through our either misinformation on magnetism or the worlds ignorance on the subject that the law of conservation of energy may still be true, although that is something I'd rather not delve into.
So what? there was a minuscule bit of energy gained, hopefully if I'm not mentally incapable. The wonderful thing about this goes back to the interactions with magnets and electricity. More importantly the fact that if you take a permanent bar magnet and wrap a coil of wire around it you can increase the magnets power with an electrical current. (you would be adding the magnets force + the pseudo electromagnets force). Throw in superconducting components which copper happens to be at very very cold temperatures and i think we're on to something!
