The bifilar pancake coil at its resonant frequency

[maxc]

I made a video about the bifilar coil experiment producing 950Vdc

Why is the distanced south reversed coil, having a much lower resonant frequency then when its normally on top.
Why do the 180 degree out of phase signals, add up?

You need to measure the input power.

Negative current moving backwards is positive current. A negative Henry is the equivalent of one Tesla of magnetic strength. Both have positive values.

The spark gap collapse is infinite, not the spark. The collapsing magnetic field generates a magnet wave that instantly reaches the most distant parts of the Universe in the Macro space and the infinite reaches of the Quantum-sphere. Tesla invented radio, and his saprk gap generator could send a signal that magnetized metal coherer filings at a distance as Marconi discovered. Tesla believed Gravity and Magnetism were twins like Maxwell electricity and light.

Jerry Bayles evolved a "Unified" field theory with gravity as a cosmological constant rather then light as Einstien with his "Special" theory. The gravity wave is immediate and instantaneous, taking no time to travel at all.

The "Black Hole" at the Galaxy's center has no space but it's huge mass is spinning faster then the speed of light. The gravity spins outward spirally like a nautilus shell describing a proportion known as PHI (1.618).  The mass of the "Spiral Galaxy" and the spatial positions of the inner planets of the solar system sit on the spiral loops. Electron shells follow suit.

I taught G.E.D. to kids with no former schooling and got mutilated here for a jug comparison to a capacitor discharge. Shameless insults were directed at me which would have resulted in a physical beating if made to my face. I demand mutual respect.

You are truly hilarious. You are once again making false claims and claims without any empirical support. As far as the "shameless insults" are concerned: Look back in this thread and see just who emitted the "shameless insults". 

You don't even realize that the Henry and the Tesla have different units, so cannot possibly be "equivalent" whether one is "negative" or not. You have no idea about the speed of "spark gap collapse" and anyone with the right equipment can prove you wrong..."infinitely".

Tesla invented radio, and his saprk (sic) gap generator could send a signal that magnetized metal coherer filings at a distance as Marconi discovered.

That is the only true statement in your whole post.

  You need to measure the input power.

My setup is far from ideal right now. The IGBT produces short sharp pulses, but, It does so by basically shorting out the power supply over the coil. and this it does 50% of the frequency. I really need to fix this, before I can make a proper measurement. The Igbt should open and close very shortly. Another challenge to overcome.

@Tinmaqn,

You call insulting someone of my advanced knowledge a 9 year old nice? I'm warning you, if you delete one more of my comments, I will initiate a new thread under a category where you have zero moderation authority.

I am an Australian,and fear not your idle threats.

I will delete any of your post that are rude insults toward other members here.

Well I am going to assume that the text that I quoted from Wikipedia was entered by someone that paraphrased the original text from a manual for an induction cooktop.  I am also going to guess that the reason the manufacturer states that is because the heating efficiency of the induction cooktop drops dramatically when using an aluminum pot, as an example.  To meet their Energy Star requirements they need to discourage consumers from using the induction cooktop the "wrong" way.  As Carroll stated, apparently some induction cooktops will not switch on if there is nothing ferromagnetic placed on them, presumably for the same reasons.

If you want to correct errors, I suggest you go to your post #579 and fix that.

I was not having a dig at you.
I was just stating that my induction cook top, has no problem firing up with any of the metals you listed.

I checked my post 579,and see no error.
Could you point it out to me ?.

Cheers
