are u useing fancy words for a magnetic core? i shall give u some time to reply, if it makes sense to me all the better. we need to be on the same page

This is straight out of one of my electronics books from school. "The effects of a closed magnetic loop is maximum concentration of magnetic lines in the magnet with minimum lines outside the core. This type of electromagnet has maximum strength in the iron ring & little flux outside. As a result, the toroidal magnet is less sensitive to induction from external magnetic fields & has little magnetic effect outside the coil. Note that, even if the winding is over only a small part of the ring, practically all the flux is in the iron core because its permeability is so much greater than that of air. The small part of the field in the air is called leakage flux."

Here is how the core & coils interact.

Look to me the primary, pickup, secondary and chokes are the same type of material.
If it is iron wire it has more resistance than copper wire.
If you look at the resistance measurements of the VIC (Dynodon provided) than you go for copper wire. (you don't want amps in the primary because the wire thickness and current is 'wasted' as heat!!!)

Material     Element/Alloy       (ohm-cmil/ft)    (microohm-cm)
Iron --------- Element -------------- 57.81 --------- 9.61 
Copper ------- Element -------------- 10.09 --------- 1.678

What the copper wire is doing is shake (voltage) the inner core material and generate magnetic pulse fields.
"Current (magnetic field) is the opposite side of voltage potential (electrostatic)"
The pulsating field is restricting the amps, what SM explains!!!
The closed loop core is providing an adding magnetic field to all the coils, so restricting more current on the right pulse frequency. That's why the current is going down on resonance.

That's what I think.  :)

Hi spintronic
Q:
the magnetic field from the primary must be perfectly uniform. if not it will leak. even a leaky primary can be shown clearly to restrict current. a correctly wound primary will read zero amps on a multimeter that measure down to 10uA (test done on my vic).
 
Any questions please post, i dont know everything unfortunately. i know this works.
end Q.

 Can you clear to my How to make the primary coil correctly in order to generate magnetic field perfectly uniform.
You mean zero amps flow thru the primary coil?
Thank for ansver
andy

The Primary windings see the impedance's of the feedback, secondary, L1, and L2 coils. So when at resonance, the primary impedance must match the impedances of all these coils in order to get a 100% transfer of energy. As for the current, once you get a significant amount of current flowing through the primary, you wont get the resonance that Stan talks about. The current will stop resonance for happening and you will have an out of resonant condition.

Hi andy
First follow the science links on electron spin orbit and understand the basics they talk of, this is important.
The spin orbits must all line up perfectly to do this the primary magnetic field must have no bends, kinks, gaps ect. It must be a very tight close wound perfect coil. not easy. The best way is to machine the spools so there is no gap formed as you first wind the wire on, you can then compress the wire without a bend appearing.
Failure to do this will mean not all electrons align. The electrons that do not will leak out into the circuit or in other words create emf. 

The good thing is we can see even a coil that leaks shows current restriction, for example by reversing the inhibit coil 178mA flows, putting the wires back the current drops to 20mA, voltage out is unaffected either way.
 
hope that helps andy with english not being your first language
