The bifilar pancake coil at its resonant frequency

[evostars]

So is this confirmation of what you said evostars--at a particular frequency the magnetic field becomes stationary?

no,  waiting for tinmans video

Ok,here is the video,and the test setup--easy for all to try.

This finding open's a can of worm's,and in the video's to come,i will show you why.

Is the value of current flowing through the center of the winding,the same as the value of current flowing into the coil ?
In this case,the answer is no,when we reach a certain frequency-and above.
It dose not have to be the resonant frequency to see this effect.

Even though we have a series circuit(resistor/coil/resistor/coil),where the two coils and two resistors are the same,R2 shows at least twice the current flowing through it,than that of R1.
TK has achieved a much higher differential between the two resistors-maybe he will post his results here. 

More to come--lets screw with ohms law

Nice can of worms!!!    Thanks for sharing that observation.

P.S. Have you tried pulsed DC (square wave) to see if the effect is the same or similar as AC ?

I don't have a BPC to play with, but this sure does look like a parallel LC phenomena where the coil has the distributed LC constants..

OK,so now the!wait for it!--overunity effect.

Dose ohms law fail in this situation?.

Below a pic of the result's, shown in the linked video below.
