The bifilar pancake coil at its resonant frequency

[skycollection 1]

I have many years sutying the pancake coils and this is my last video about my "multifilar pancake coil", this consist in six groups of pancake coils, one group consist in six pancake coils connected in series, all the groups are isolated from each other and all the pancake coils are in parallel in the same place (in a PBC PIPE) in my experiment i am using my circuit JL94 with two transistors like the drawing diagram that i am presenting in my video, when i move a magnet in the centre the circuit and the coils "enters in self oscillation" and all the groups "induces" the current to the led bulbs with great intensity, i have connected to the circuit only one group of pancake coils, the other groups are "pickup coils".
this is the experiment...: https://www.youtube.com/watch?v=0Ln7AEpxMeY

"When the magnet is moved away, current flows in the opposite direction in the solenoid".

Is that your "definition" of Negative Current?

Then you should be happy to admit, finally, that my demonstrations prove that there is NO "NEGATIVE CURRENT" or current flowing in the opposite direction when the magnetic field of a coil collapses when power is interrupted.

If you still refuse to acknowledge that you are wrong, please explain why the Blue LED flashes (showing current definitely flowing in same direction) but the Green LED does not flash (showing that current definitely does NOT flow in the opposite or reversed direction). 

Be sure to include in your explanation the fact that the Green LED actually has a lower V_fwd than the Blue LED, so is more sensitive.

Thanks for share Jorge i'm a fan of your work in last years .
All the best to you

Dear evostars.

I had a little fun with this one from Nelson.

As did a few others, we all found interesting/different results.   

Cheers Graham.

Hi dear Grumage ,
I didn't know that you replicate the circuit , and i thank by that because only very few people test it  . hope you like it and could help you learn some interesting aspects that circuit could show  .

Take careful , to avoid hear that you are using  super capacitors, disguised as normal capacitors, to the oscillations continue after power source be disconnected myself hear thousands times that

cheers

I think, Nelson Rocha's circuit would deserve it's own thread - if anything else than because it doesn't contain pancake coil (according to its diagram this coil even isn't bifilar) and it's the only selfrunner in the wild and also author communicating at overunity.com forum in this moment (i.e. of much higher importance than some abstract discussion and frog&mice battles about interpretation of well understood phenomena). For me it looks like Joule Thief circuit with ferroresonance overunity.
