To better help visualize the field lines structure of a bar magnet, I found something that Nassim Haramein used in one of his presentation:
The perceived motion of field lines are represented by connecting the moving dots. If we take out of the picture the continuous vertical lines, with what remains if we copy/paste then around the torus, the spiral shaped lines represent the magnetic field of both poles. The fact that this figure comes close, but not close enough to what I want to describe, makes me not to assign it with a number.
And again, nothing moves. It is all potential. In fact, this is the basis of today blurb.
Exactly like in the Figure 12 (except this is for a bar magnet), the illusion is there. If an observer keeps staring at one point, it becomes obvious that is all static. The moment the eyes start wandering it all becomes motion.
This why I say is static and in the same time, potential. It does nothing until the opportunity for manifesting that potential occurs. And that opportunity will induce the sensation of motion. It is like field lines are frozen while it has the memory of motion. All is needed is some moving observer.
As a perfect example, as I see it, is the Homopolar Generator. It has been invented by Faraday:
Figure 16.
It has come to my attention that it can be even more simple. It has not to have two poles on each side of the disk, but that thing will make it more efficient.
By visiting “Homopolar Generators” section at the page: Homopolar Motors and Homopolar Generators. From Physclips: Mechanics with animations and film. you can have a description and even some clips with some demonstrations.
Figure 17.
What we can observe is that just the relative motion (rotation) of the copper disk in top of the magnet bar will induce the potential which can be collected at the brushes.
In other words, the static potential exhibited by the magnetic filed is transferred to the brushes (as dynamic potential) once the magnet perceived the motion. Like I said with regard to Figure 12, once the eyes wander across the picture, that static potential is induced as electrical signals in our nervous system which in turn give us the illusion of motion.
As we do this to ourselves, the same, the disc is generating that electricity, by using the motionless power of static potential.
Another motion directions are possible too but after brief consideration, the relative speed being too small, the effects are not significant.
From the page I suggested to visit, there is also an explanation on why this is happening. In just one word: Lenz. So we have no need to repudiate that law, when we see that actually is helping generate electric power. We may need instead to consider changing our ways of thinking and find new ways to harvest that power in that simple way from more evolved electric machines. But that doesn't mean I have the answer. I am sure though that someone out there reading this may be inspired and in a flash it will pop in mind's lab the solution. And when it will be maid public, everybody will reflect upon simplicity and think “Man, I was just 2 seconds behind!”
I hardly can wait for that day.
