I think it is normally considered to be neglected, because Id's value is very very low (under "normal" conditions that is)

Yes, that's the point. The formula is assuming the permittivity and permeability of empty space as norm. Change that to higher permeability materials, add capacitance and things change IF there is also flux CHANGE over time. You just cannot neglect such things.

You shouldn't have posted that. I will never get offline now. This stuff is just too interesting. Girl is calling me nerd already.

I've been out testing the multi filler (5), connecting in different ways. And each way puts out a different wave form. But the most interesting connection was a continuous series connection. It is hard to explaine but I will try.
5 wires on each coil we'll call a-e and T or B for top/bottom coil.
from the fwbr to the coils then back
T/a start
T/a end to B/a end
B/a start to T/b start
T/b end to B/b end
B/b start to T/c start
T/c end to B/c end
B/c start to T/d start
T/d end to B/d end
B/d start to T/e start
T/e end to B/e end
B/e start to FWBR

I am sure that doesn't make much sense, I will try to draw it on something to post it. Any way this configuration seems to fill the cap to highest volts (7.5) and has an odd scope trace, have a look

That picture scope is connected at FWBR dc output to 12leds.

Added a cap

this one I hooked up the load as motor was speeding up and we are seeing the slow down

With no load the voltage was off the screen top and bottom
Also with no load I can get the cap to almost 14 volts.

edit: this configuration does add drag and can be offset by the bias magnets
but also gets the leds the brightest so far.

So 7.5 Volts under load for the coil pair? At what RPM and input voltage?

For the people interested in comparing coil output
a small convention would be nice.
Since everybody is using different loads, it`s difficult to
get a quantitative understanding of the power produced when looking
at cap voltages.

For that it is required to know what current is being drawn at what voltage.

Would it be appropriate to maybe just use a 1 Ohm Resistor behind the FWBR and measure the current with a multimeter in series?
The voltage would be measured across the resistor. And the product would give a rough number for the power.

 I found the cause of the odd wave form... it was a poor connection to one of the coil wires. I was wiggling them and noticed the output go normal then motor started hauling ass as I completely pulled the wire off.
I agree that it would be nice if there were some consistencies between all of us a 1ohm resister as common load sounds like a great place to start.

maybe a common spread sheet too?

Hi guys!

Great stuff from everyone!

Just made another video; please take a look  http://www.youtube.com/watch?v=SUcU2vaL77Y
