DIY Flapjack Coil Jig

I am going to run it with 120 VAC from my ElectroMechanical Inverter...

I was only going to apply DC only to look at the magnetic field...

Its a transformer, so yeah the current has to be wiggling to get the effect...

I think AC will do the trick as well as the filings or w/e will not physically flip over, I assume?. Although I was interested in the pancake on its own for another project I'm working/thinking of.

There are many alternate applications of the flapjack coil...

There is a reason Tesla was interested in these, lets find out...

Accretion of electrons happens in the equatorial orbital plane of the magnetic field.  The flapjack coil energized by itself (I think) will still develop a magnetic field with the same major axis (where the red coil is now).  But will collect the energy that it puts into the magnetic field back onto itself.  So the result would be an extra large back EMF.  This is because the coil sits on the equatorial orbital plane of the magnetic field, and collects the accretion of electrons formed in the field.  Think about this, the major axis is formed in the center of the loops of wire, perpendicular to the windings.  So the Flapjack coil would generate an abnormal amount of back EMF, which would make it good for one of those battery charger things like a Bedini circuit...

Congratulations @zmonkey

That work is finished and ready to test!

Pancake coils are a bit unique in that polarity is radial. i.e. North in the center and South at the outer diameter.

Apply some current to that pancake coil and test it with a compass. You will see what I mean.
I agree with most of what you say but not with the polarity part.
