The bifilar pancake coil at its resonant frequency

[TinselKoala]

Yes.  Probably the best would be square profile enamel wire. Also comes in a rectangular kind also. That would increase surface area proximity between windings.  In Telsas drawing of the series bifi is seems to show some heavy insulation, but that doesnt change the fact that it could be better.

Exactly!

I was referring to your reply to my post about resistance on that and you said "exactly Mags"  Ill look it up if need be.

On what you quoted me on above, Im just relaying what Tesla says in the pat on electromagnets.  The inductance is ignored by the input and the only current limiting factor over time is the coils resistance. So it was the resistance part that you agreed with me on that the currents through a non inductive resistor has no delay in reaching max current V/R. Soo, if Teslas claim is correct then if we pulse the bifi coil, the only thing the input sees is the resistance and if the current reaches max instantly then what of the magnetic field it generated?  Its a short read. So why not investigate THAT claim?

OK, I see what you mean now. It's a good question but difficult to answer experimentally. I'll see what I can do.
But you have to remember that there are different kinds of "non inductive resistors". There are wirewound resistors that use special windings like hairpin bifilar and Ayrton-Perry, whose magnetic fields do exist but cancel in the bulk due to the proximity of the windings carrying currents in opposite directions. There are carbon composition resistors that have no windings at all. There are flat resistors with special partial conductive materials that also have no windings at all.

ok,below is my bifilar coil.
It is made from heavy gauge rectangular ali enameled wire-so the winds sit nice and neat together.

I am just running an AC current through it,via my SG-so very low powered.

But here is the kicker,after a quick 10 minutes of testing.

The voltage generated across the sniffer coil,is in phase with the voltage across the bifilar coil,and not in phase with the current through the bifilar coil. The current through the bifilar coil is 90* out of phase with both the voltage across the bifilar and sniffer coils 

Tomorrow i will wind a single layer coil of the same amount of turns,and see if it is the same.

BITCH !!

And... by the way... capacitors take time to build an electric field and charge up to a given voltage, and inductors take time to build a magnetic field and pass a given current. Nothing happens instantaneously.

I understand that. But with a bifi, is it different than what you posted above. His pat clearly states differently than you quote above. Like I said, its a very quick read. So lets test his claim. Or is it your opinion that he was terribly mistaken as you have read it already and took note of the claim? Just askin.
