I think BEP understands this too.

The reason why I want to find out is because of this.

I did not want to say anything yet, but I am having a tremendous success!!!!!!

Howdy,
That is quite a long thread.  I need to read through it to understand what you are doing...

My goal here is to run a motor with a 1.5v or 9v battery and charge the battery while running the motor.
So you are making something similar to a Bedini Charger.  Use the Back EMF to recharge the drive battery?  Recycle that energy, good job...

As long as you keep the pancake at ONE (1) layer the poles will be radial. The problem with poles is there are none  ;)
Magnetic flux goes in a recirculating flow. Compasses only align themselves with the flow. They don't point to a pole. No different than a flag in the wind.

This is why Earth generally has more than one of each magnetic pole. Putting two wires side by side concentrate the flux along the axis between the centers of those two or more wires. So, two or more layers and the pancake starts looking like a common solenoid coil.

The real beauty of this type of coil is it tells Lenz to blow. The induced field is perpendicular to the approaching field instead of opposing.
Bang one of these with a sharp spike and there is a 'clapping' in the center like no other. It is like stomping on a ripe banana. Everything squirts out the axis.

Ever wonder why Tesla coils work? Ever think about putting two separate secondaries on one? One above and one below the primary pancake coil.
It can be very enLightning!

I agree that pancake coils can do interesting things. But you are ahead of me on those things  ;D. I'll try and think of more things that can be done with pancake coils.

Edit: Attached is a simulation I just did of a cross section of TWO pancake coils on top of each other. As suspected the field is nicely radial in the middle (red area). I'm still figuring out its mechanics a bit. The past few days I stopped looking at the law of induction and started solely looking at coils from the perspective of the Lorentz force. Which gives for interesting realizations.

Another thing I was asking myself a few days ago was "how can one make an instantaneous magnetic field". In other words how can a coil produce a magnetic field without any back emf. And the pancake coil seems to be the answer. It acts just like a resistor but gives you a magnetic field as a bonus without any "charge time".
