STILL DON'T HAVE THE INSERT IMAGE PROTOCALL DOWN JUST YET - EH I_RON?

@Thane,
Your 1A NON WORKING COIL has the rear core flat bar in a vertical position. I'm not sure of the forward cores orientation from the picture, but the rear core flat bar would have to be in a horizontal position with the forward core in a horizontal position to pass the maximum flux.

From my testing of regular steel laminate positioning, I think the vertical position with obvious warped air gaps would ensure that very little flux is passed between bars.

Regards,
Larry

THANKS LARRY,

TOMORROW I AM GOING TO TRIM OFF THE FERROMAGNETIC ENDS OF COIL 1A AND MOUNT IT ON AN ALUMINUM PLATE.

THANKS FOR MAKING ME LOOK AT IT AGIAN!

YOU KNOW WHAT - THIS IS THE MOST INCORRECT THING YOU HAVE EVER SAID.

Nice to know I am in top form!

YOU CANNOT USE ONE MAGNETIC FIELD TO CANCEL ANOTHER

It depends on what you mean by cancel, both fields are there but they sum to zero.
their existence becomes theoretical as both are opposite and in the same space, they have the exact opposite effects on anything that responds to a magnetic field.

Now in the example here they do not cancel fully, but the generator coil does significantly reduce the net magnetic influence.

- MAGNETIC FIELDS ALWAYS FOLLOW THE PATH OF LEAST RELUCTANCE IN AIR AND INSIDE METAL.

Actually they don't follow anything, Magnetic fields to not bend or react to other magnetic fields, their fields simply sum to make it appear so.
But even if we take the slightly inaccurate (layman) point of view that they do the simple fact is that the magnetic field from the rotor is pushed out of the stator core partly by the magnetic field of the coil.

INCREASING FLUX MAGNITUDES INCREASE CORE RELUCTANCE WHICH GIVES THE IMPRESSION OF "CANCELLATION" BUT IT IS NOT SO. TO SUGGEST OTHERWISE IS A GROS MISUNDERSTANDING.

TAKE TWO SEPERATED IDENTICAL ELECTROMAGNETS POINT THEM AT EACH OTHER IN AIR - AND TELL US THE FIELDS CANCEL? ABSURD

At the mid point there is indeed perfect cancellation.
But more practically the 2 coils reduce the strength of each others field.
If you brought them closer and closer until they were both superimposed on top of each other there would be zero net observable field. (a bucking bifilar)

NOW POINT THEM AT EACH OTHER THROUGH A METAL BLOCK - WILL THEY CANCEL EACH OTHER - NO WAY! THEY MAY SATURATE OUT INTO THE AIR BUT NEVER CANCEL.

The magnetic field in the exact center will again be canceled, the field elsewhere will be somewhat lessened.
I think you are getting a bee in your bonnet over the term canceled.

The simple fact is that the generator coils reduce the observable rotor flux present in the core.

I will reply to the rest in another post.

I AGREE YOU DON'T MEAN "CANCELLED FIELDS" YOU MEAN "CANCELLED EFFECTS" ON A COIL - SUCH THAT TWO IDENTICAL OPPOSING FIELDS PASSING THOUGH A COIL WILL NOT INDUCE A CHANGE IN FLUX IN THE COIL BECAUSE THE "CHANGE" AS SEEN BY THE COIL IS ALWAYS NET ZERO. RIGHT?

Right.
