Hey Peter
here is the way back explanation.
http://www.overunityresearch.com/index.php?topic=827.msg13895#msg13895At the time I was envisioning the bias mag in the mix but the same ideas.
Look into Faraday. . The field must cut the conductor to induce currents. Now apply that to the coils you are using.
If the core was not there, the field would be able to go all the way through the coil as a whole giving a lot less output due to both sides of the coil are being induced by the magnet more than without the core acting as a barrier between the incoming and outgoing side of the coil.
This is general as to the way the magnet approaches the coil from the side and leaves to the side of the coil.
Now, if w have a magnet at tdc and moved the mag up and down, inline with the core/coil, we would have generation also due to the flux is not moving perpendicular to the axis of the coil, it will be oscillating from front to back of the coil not left and right.
Anyways, I apologize to EM. i just got a lil frustrated with the "disinfo" thing when it was really the other way around but nobody paid attention. So now we are clear on what is happening on how the magnet generates current in the configuration we have. ;]
Im doing some tests on my bifi that may show why the magnet spacing is necessary to eliminate lenz, but the mag, at the right speed, rpm, hz, can tickle the bifi ito a resonant state for at least one cycle(due to load killing the resonance). The one cycle at the right(resonant) freq will generate more out, because it is easy when the freq is right..
The bifi is an inductor with greater internal capacitance than a normal coil. It will have a resonant freq, and harmonics there of. I believe that Romeros gen coils(bifi and confirmed) may only be hitting a lower harmonic, as I dont see his coils havong a resonant freq of near 160hz. For example, 1200 rpm x 8 mags = 9600 passes per min divide by 60sec = 160hz. And that figure may be higher because the magnetic induction event is not an even flow on the rotor. Remember the flat spot. ;] its just an estemate to get the idea.
We will see tonight hopefully, and will post results here and at OU.
Let me know if you think Im wrong with any of this and I will explain further. ;]
