More coil related questions:

I can find out the resonant freq of a primary, by using this method:

http://www.hvtesla.com/img/tesla%20coil%20tuning_prim.jpg

Then I can make the secondary so that it also resonates with that frequency.

Now what if I have a 15kV flyback transformer to drive the primary? How do I measure my primary to resonate to the freq that the flyback produces? Or do I just connect a cap and spark gap to the circuit and change the cap values to find the resonance? What methods can I use to find that resonance, because I can't just connect an oscilloscope to a coil that has 15kV running through it? If I use another coil, maybe just few turns, and hold it near the primary. I can see spikes, but doesn't this just show the resonant freq of the short coil that i'm holding and not the primary's resonance?

Pretty much from your original request here, if your primary is of lower turns and lower inductance than the secondary, you would need to measure the secondary self resonance and then the primary self resonance. The primary will have a higher freq of self resonance, so if the primary were a bifilar coil, then there would be more capacitance in the primary windings which would lower the primary self resonant freq. Not sure of the gap between the 2 freq the flyback would be here, but Im guessing more that just making a bifi primary wouldnt help. So now you could add capacitance externally to the primary and if it is the right value, you can bring the primary resonance down to the same freq as the secondary self resonance.

I get it. You want the resonance of the primary to match the sec and experiment with that.

I wonder if there are steps to take that make this easier? Like make sure the primary is 1/4 of the secondary length or does that even matter if you start adding capacitance manually to the prim coil?

What if I just make the secondary from bare wire and just change the pickup point to where it resonates?

Then have the prim coil inside it

Now if these are magnetically coupled https://www.youtube.com/watch?v=-b7LDtsaS8Y

Does it mean the electric field goes out from the sides of the coil and magnetic field from the ends of the coils?

If they get 95% efficiency from coil to coil what happens if you also have another receiving coil on the other side of the transmission coil? Don smith said you can copy the magnetic effect as many times you want without increase on the input. Was the full of shit?

I was just wondering if this is what TK is doing and not pulsing coils with kachers or else+

There are 2 kinds of resonance.

One is the normal known, a resonance between the dielectric and magnetic field energy in a coil.

The second one is different. it is also based on dielectric resonance. but its counter part isnt the well known magnetic field.
Its a different kind of field, that has no magnetic properties.

Resonance is the transformation from one energy form into another, and back and forth. just like a swing.

The sine wave of the dielectric field (measured in voltage) can be measured easily with a scope. when the voltage becomes zero, it means the dielectric field energy is zero, so it has been transformed 100% into the magnetic field energy, in the first kind of resonance.
The magnetic field can also be seen and measured. With a gauss meter, or simply by a compass, near the coil. It will deviate, when at resonance.

But in the second kind of resonance the needle doesnt deviate, and the gauss meter is not measuring a magnetic field strength.
But, the voltage does become zero. the energy can't just disappear and reappear. So there must be a 3rd kind of field, where it is resonating with.

I see the dielectic field, as ropes of twisted eather, between the windings of a coil (capacitance).
A magnetic field, I see as a Aether vortex.
The third field, I think is like a ring vortex (like dolphins blow vortex rings).

The magnetic field, and the 3rd field, look almost the same.
the magnetic vortex, twists inside in a spiral.
The 3rd field ring vortex twists inside as a circle.

How, to create the 2 kinds of resonance?
I use pancake bifilar coils, series connected, because they have increased capacitance, en therefor can store more energy in their dielectric fields. This makes the resonant frequency of the coil lower.

The first resonance, is created by using 2 of these pancake coils, stacked in parallel.
One is pulsed with dc, and the other is grounded at one side, and probed at the other side. this coil is resonant, if the frequency of the pulses is at the resonant frequency of the resonant coil.

The second resonance, is created differently.
I still use the same two (biPHIlar) coils. But now they are separated. (so the first resonance doesn't happen).
The first coil is still pulsed at the resonant frequency of the resonant frequency of the second coil.
But now, we use the back emf, created by the collapse of the magnetic field of the first coil, when the pulse is going to zero.
This Back emf, voltage spike, is fed into the second coil via a diode.

Now the resonance is different. now there still is the voltage, but the magnetic field isnt detected anymore.
I think it is, because it is hit like a hammer on a bell. The back emf spike, is direct instant energy. resulting in a ring vortex.
Just like sound is longitudinal. the ring vortex created, represents a longitudinal field.

To increase the back emf pulse, I increase the inductance of the coil, by adding MnZn ferrite.
I also increase the current into the first coil.
And I increase the duration of the pulse, by using a depletion mode mosfet.

This d-type mosfet passes current, when no signal is applied.
The signal I use to interrupt the current, is another back emf, at the gate of the mosfet.
This quickly turns the mosfet off and on again.
This makes it possible, to combine BOTH resonances in the second coil (when it is placed in parallel with the first coil)

On another thread there was talk about cold electricity, that it could be coherent electricity or fields like laser is for light. Could this what you are describing be coherent field?
