The new generator no effect counter B. EMF part 2 ( Selfrunning )

Actually, what I was trying to ask is, do you think any of these waveform would make a difference if this was a generator output and if so,  why?

Hi Luc,

Regarding your question: I assume you are curious whether such kind of setup may make a low drag or a low Lenz kind of generator?
Well the short answer is that I do not know for sure. A bit longer response, though it still will not give a definite answer, would be this: 
Lets find out what happens when your coil is loaded? My guess is that it might be a low Lenz setup because the counter flux from the load current seems to make the coil core less 'attractable' by the magnet flux than in the unloaded case.

When your coil is not loaded the U shape core needs a certain input power to keep it in motion, the drag against the motion is the attract force the magnets flux causes by "jumping" back and force between the coil core and the moving core. OF course this drag or rather a mechanical cogging can be minimized by clever mechanical setup.

When your coil is loaded the counter flux by the load current should work against the magnets flux, reducing the attract force by the magnets flux I think.  This may unbalance the earlier mechanical balance (of the unloaded case) in the cogging issue and may reduce a little the input power to the prime mover (this latter sounds good). Again, this effect may be compensated too but the phenomena may introduce load dependence.
The limits of flux density in the cores are to be considered, including the load current, to avoid or at least reduce core saturation.
All in all, my guess is this generator setup may have a low Lenz effect, and whether this is already enough for a COP>1 performance can only be answered by trial and error, unfortunately.
If I still have not answered your question, then please ask for the third time too but please rephrase it a little. 

Regarding your repositioning the magnets test: waveforms are widened, but the basic waveforms stay, whether the average power in the previous and in this latest waveforms is similar or not: by the look of the curves the areas covered look more or less similar to me. How a waveform wider in time duration may influence or not influence for instance Lenz law behaviour: common sense says Lenz law follows suit...   but again this is to be tested.

Hi Gyula,

you answered my question well, thank you.

Below are some new Scope Shots. First open coil, then 100, 50, 25 and 12.5 Ohms loads with Power calculation included included

So I was messing about with one of those "shaded pole" motors that I got from a microwave oven fan. Thinking about what Gerard morin was doing with his little pump generator I replace the steel rotor with a 1" axial  neo cylinder and I spun it up. I got 110v or so before the axle slipped.
My question is why could this not simply be reversed for the gen we are working on in this thread? Why individual steel rotors and not just a single round one that spins in a n/s field.

Just wondering if you confirmed your results yet with current measurements on the input, rather than relying on the sound of the motor?
