Secondly a tiny bitsy question if I may: what the hell makes a coil have it's very own natural self resonant frequency? And again, is this an universal constant?

Only for daring people, trolls have to wait for the answer and report the trend.

There is capacitance within the coil between windings. So all coils, bifi or normal winding, are LC circuits.  You can see it on a scope across an inductor with power applied to the coil then releasing the input. There is not only a spike, but if there is nowhere for the spike to go, you will see the oscillation. It is more pronounced and lower resonant freq if it is bifi winding due to more capacitance to hold charge before the input is taken away.   That has me thinking....

One issue is when we disconnect power from the coil, some or say most of what was stored can escape through spark of the switch, diode to suppress, resistive load, all will dampen the coils oscillation. And its probably hard to get a mechanical switch to open fast enough to beat the collapsing field to avoid sparks across the gap.
But, if say we had a bifi coil that has a lot of capacitance, and when we release the input, the collapse time should be slower due to lower coil resonant freq, of which would hopefully help delay sparking while switch is opening. If it is possible, when you release the input from this coil, if there is no spark loss, the oscillations should be much better than normal circumstances where the collapse is just dampened hard buy say rectifying to a cap and such.  dunno on this part yet. Just thinking

You refer to the parasitic capacity....capacity which owes its existence to proximity between turns.  This is not the true capacity of the coil.

Just the capacitance value. In a bifi the total capacitance is much greater than a single wire coil. So the resonant freq of the coil itself will be much lower than the single wire coil, of the same dimensions and such.

Along with the inductors inductance storage, the larger capacitance adds to the coils total storage. No?

You have no problem identifying with a real value as it relates to inductance......I only ask you to consider identifying a real value as it relates to capacity. 


What is capacity?  Knowing what it is in this context, may shed light on why it is not limited to proximity between turns.  I am not concerned with the difference between bifilar single wound inductors, I am only interested in identifying what capacity is, where it is, why it is, and all of this for the purpose of obtaining that which matters most to me.....

I get that the capacitance of a coil, normal or bifi can be seen as a much more complicated thing than just the interaction between 2 adjacent turns. You can pulse the coil and scope it and find the resonant freq and calculate the actual capacitance in action. Otherwise it might be tough figuring a single winding coil otherwise.
Bifi has the unusual voltage differences between adjacent turns and beyond, vs a normal coil.

But I think I described what he wanted to know in my first post above.

An interesting use of the term capacity can also be seen at Daniel's mac Farland Cook patent.

... the action then in either the simple or compound helices increases in quantity to the maximum capacity of the wires to conduct with the existing tension of the current....
