Some Bifilar coil experiments

Hi Teslonian,

Very good job on the picture size, now it perfectly fits, thank you.

I wish Marc could learn about the other parts of my above post too...

Im building Nelson Rocha's circuit he has posted a few years ago. In search for high voltage hairpin impulses.

Tr2 is a step up tranformer (230V-5V in reverse)

capacitors at the base and the 4700pF need to bee 400V rating
diodes ultra fast.

the ring toroid 1:1 is a joulethief with the darlington. creating pulses in the step up transformer.

waiting for some parts...

with high enough current/voltage the sine wave (expected) transforms into pulses (i hope...)

When pulsed from both ends, at the same time, but with opposite polarity pulses, We still have a dielectric voltage rise, but now with the absence of the normally observed"static" magnetic field  (seen with a compass) at resonant frequency.

We ring a bell, with a strong impulse, short and energetic. thats why I need hairpin pulses, with high voltage.

We are use to inductive power. but this coil is about capacitive power.

MAgnetic fields are the LOSS of the dielectric field. When we spend energy we produce magnetic fields.

So to CREATE energy we need to stay away from producing magnetic fields, we need to produce strong dielectric fields (something the bifilar pancake tesla coil excels in).

to use the standing wave, it needs to be 180 degrees out of phase (2 resonating coils).
This can be understood by looking at 2 equal ropes. that slap together at 180 degrees out of phase, the complete rope clashes together, producing a big slap. 

I like to use a center tap, so the coils become whips. producing even higher voltage. (2 coils series connected in the middle, to ground, so the outside ends are 180 degrees out of phase).

the bang it produces with High voltage, bounces back....

When the dielectric field energy is rectified, and captured in capacitors, it can then be transformed into lower voltage.

Can someone explain to me WHY the primary bifilar non inductive coil can light up a LED when led is connected to secondary solenoid coil?  the non inductive coil is non inductive coil or not ??

Have you seen Jack Noskills' coilcap where 2 coils both have an open end and you pulse them. He says there is no regular induction because of the open ended coils. There is supposed to be just capacitance and no flowing charge. They are done bifilar
