The bifilar pancake coil at its resonant frequency

[TinselKoala]

@Mags: Sometimes the "best" mutual induction is not the "greatest" mutual induction. Rather loose coupling is required for better performance of certain (ahem) air core quarter-wave resonant transformer systems that take advantage of VRSWR.

Note the very specific claims in this video by TheOldScientist about the _DC Resistance_  and the _Inductance_ of the single layer Tesla Bifilar solenoid coil he tests in comparison to the single layer monofilar coil with the same amount of wire. And note that he does not allow comments on this video.

I'll have more to say about this, once people have watched and commented here about these specific measurements made by TOS.

Please continue this argument by yourself.  I have no use for you, nor your opinions.

There is a difference between asking a question and expressing an opinion. Why don't you just answer the questions that have been asked?

I know why, and you do too.

MH asked,

exactly what is special about the bifilar coil and how you can apply that to accomplish something practical in the real world

[Grumage]

Dear All.

I have attached a pdf file from 2011.

Now before you all start lining up with the " butcher knives " did anyone, anywhere try this?

Wouldn't it be an interesting project to prove practically?

Cheers Graham.

He is certainly a lot more of an authority than YOU claim to be.



I've got some news for you, genius. The Ampere-hour is not a measure of CURRENT.
Figure it out: An Ampere is a Coulomb of charge per second. So the units of the Ampere-hour are (Coulombs/second) x 60 seconds per minute x 60 minutes per hour = 3600 Coulombs. The Ampere-Hour is a measure of CHARGE.


See the wiki if you don't believe me. Units are important! At least to people who actually understand them.

@Tinselkoala,

Now you're outsmarting everyone again as a big genius on some technicality when you stated repeatedly that the Tesla and Henry
were like apples and eggs. You never understood anything about inductance the entire time. You proved that by your comments. No one's willing to use you any longer to teach here at the Overunity site. It's too late. Youv've been exposed as a fake for all time. 

That's not your only area of complete ignorance: You challenge the vortex PHI theory of Electro Gravitation, and apply Square exponent "Frequency Spectrum" math to spiral 1.618 ratios of magnetism. You challenge the "Unified Field Theory" and on top of that you're a "copy and paste" addict who covers his ignorance with insults and abuse. 

You want me to discuss the units of charge, implying that I'm the one who has no understanding of inductance, while you continue to confuse everybody.

An Inductor with a measured inductance of 1 Henry will generate a magnetic field if 1 Tesla in flux density with a fixed current input. Now you pretend you are better to determine what that factor is than I am after quoting things from Citfa like Henries are bananas not monkeys and reams of other utterly ridiculous things.

Now that I towed you and your "Lug of Nuts" this far, go ahead and tell us just exactly how much current it would take to generate 1 Tesla of magnetic flux in an inductor of 1 Henry of measured inductance. Pray tell us now Mr. I.Q.!

Don't accuse Synchro1 of "Flipping the Drag Bail" on you for continued play. Everyone knows as you say: "How important these units are"!
