Oscillating sine wave LC tank magnet motor.

@MarkE,


             Maybe you should go back and re-read the comment. The "Old Scientist" reports that the external capacitor does not have a major influence
on the "Series Bifilar Coil" as you infer! There's an additive formula for the twin capacitors in the Colpitt oscillating circuit that won't work on the bifilar tank as you imply. You're making a mistake!

No, you are once again doing your misrepresenting thing. MarkE is correct in his explanations. If you want to know the real story of lumped vs distributed capacitance in TBF windings you really need to read the work of the Corum brothers.
It is simply not true that "the external capacitor does not have a major influence" on the TBF coil's resonance or other characteristics. You are misrepresenting the experiments and conclusions of Old Scientist just as you do with the work of others.
I give you once again the diagram that shows the relationship between inductive reactance, capacitive reactance, and the resonant frequency of _any_ LC tank, including those that use TBF windings. The reason OldScientist is confused is that he appears not to understand the things that the Corums have explained wrt distributed vs lumped capacitances.

There's an additive formula for the twin capacitors in the Colpitts oscillating circuit that won't work on the bifilar tank as you imply. You're making a mistake! Capacitance is evenly distributed in the series bifilar unlike the external capacitor that's wired across a divide of calculated resistance.


Quote from the "Old Scientist":


                            "It seams that the Bifilar coil does not participate in the dependence of (external) capacitance".

          Wiring a separate capacitor to a series bifilar coil does not behave additively like wiring two capacitors in parallel to a regular coil. The unequal distribution of capacitance between the bifilar coil and the external capacitor precludes the use of the standard formulas you're falsley trying to apply!

We have been discussing your use of a meaningless term. 

The quote you cite is a silly one disproven by 150 years of electrodynamics.  I can show you bifilar wound coils all day long that completely conform to simple analysis.

Please refresh my memory and show me what formula it is that I am trying to incorrectly apply to what situation.

@TinselKoala,

Are you threatening me, or just expressing your wishes?

Why don't you try _refuting_ me with checkable and valid outside references, facts, or demonstrations of your own? I know why and so do many of the rest of us. You cannot.

@TinselKoala,


Because you're BULLSHIT! Stay off my thread!
