New coil, same results...  Have to try again with bailing wire...

From the picture of your setup the scope shows 5Vpp on the output of your AVR but the real voltage of the pulses across the control coils must be much less: your control coils may have about 1R resistance connected in series with 330R resistor - you get current about 15mA which gives 15mV across 1ohm control coil.
Can this be right that 15mVpp on the control coils generate 7Vpp on the collector?

"The multiple frequencies traveling around the coils are of too high a frequency to provide for any motive effort. They are only a means to achieve an end. The multiple frequencies begin to feed themselves..."

So, what does he mean by a means to an end?  That two high frequencys are used to generate a 3rd beat frequency which is much lower?

I submit to you that the extra energy being picked up by the collector coils might not be a result of coupling, but the manifestation of another phenomena. Think about it...

Jacob if you have something to say, say it.

I have just tried the same setup as before but with a sinewave input instead of a transistor and pulse.

The compass still spins with two coils and one AC signal.  It will work much better with another two coils and 90 degree phase shift.

The more I think about it, it must be wired like to this to get a compass to spin.  And it looks like a phase motor!

Dave, when you get 4 spools set up, throw a speaker wire in the center, through the holes in the spools, if you have some, and see what you get out of it, if anything. Also, try DC pulses, just for grins and giggles if you get a chance.
