The magnetic field depends on the product (multiplication) of the number of turns and the current amperage in the turns. The current amperage for a given applied voltage will depend on the resistance of the wire. Fine wires have greater resistance per unit length than heavy wires do. So there is a tradeoff between number of turns, thickness of wire (resistance per unit length) and magnetic field produced.

You touched very important topic ! The battle is about the choke which is high inductance yet very low ohmic resistance.
Any thoughts ? I have one and if you guess close to mine concept I will open source it here and for ever  ;)

Hey guys
If you cut the coil and supplying it the way you describe, then every turn will have  the same voltage potential and there is no step up or step down effects like coils. It is something else. It is like a superconductor with resistance close to zero but it is a straight conductor and not a coil. Perhaps a coil with every turn consist of hundreds of thin wires fits better to what you are trying to describe.

No!!!   I agree with TK :-  "So there is a tradeoff between number of turns, thickness of wire (resistance per unit length) and magnetic field produced."

If you make any inductance of low ohmic resistance it will become a short circuit and you will not be able to maintain required voltage and current in the choke.

I have shown only one coil in my drawing.  If you connect several such coils in series or parallel, then you may get some resistance to maintain required voltage and current.

Hi All,
There are some things that I observed:

- From the first period transceiver radio , inductors used are silver plated copper core here .

- In the resonant coil of Don Smith's devices High - Power Devices : Coils that we see in the video is performed silver plated copper wire core .

- Dally free energy device has an outer coils of brown ( http://img0.liveinternet.ru/images/attach/c/6/91/684/91684490_100_6334.JPG, http://img1.liveinternet.ru/images/attach/c/6/91/684/91684491_100_6335.JPG ) related to the type of electrical wires are insulated shell it has asbestos fibers, core multi- core copper clad silver conductive, wires are used in military equipment.

- Recently ( Russian Scientists made Tesla Generator ENG SUB ) have made ​​a resonant coil -like structure resonance coils Don Smith's .

You will no longer funny when people try to replicate as Don Smith's devices, Kapanadze ,  Dally . . . That we may have inadvertently omitted an important structural core of the coil resonance of the device is re- created !   :D

How about making a lengthy track of bundled insulated copper wires and run a magnetic train on it??!!

There is no need to keep the cut coil only in straight condition.  When it is bent in the form of a circle, it produces strong magnetic field at the center just as a normal coil does.
 
I have designed a funny transformer based on this principle.  Just have a look and have some fun!

The idea of using a single wire in a coil is to ensure flow of current  through all turns from one end to the other.   If you cut a coil and apply voltage at open ends,  current may not flow through all wires.  It may flow through few wires choosing path of least resistance.  In that case you have to use very thin wires having some resistance to ensure that current flows through all wires.

Did anybody try this experiment?

Hi folks, Hi vineet, thanks for sharing your thoughts, I think I see what you are getting at.
Using a mechanical analogy, your idea is to use a high torque input or low gearing to move or excite the secondary, then the secondary output will be far more voltage oriented and be a low torque, high gearing.
This means, that the secondary cannot push back on the high torque lever or gear, nearly as much as in the typical transformer setup.
Whether this idea truly does what is hoped, will have to be tested.
The only issue I see is, is that even though the secondary is higher voltage and lower current, wouldn't that secondary magnetic field be just about as strong as the primary field, requiring more input as we extract output.
Again, since this idea seems to be different, it needs to be tested to see.
peace love light

@SkyWatcher123
 
 
In a normal transformer as you said the secondary magnetic field remains the same irrespective of number of turns.  Only voltage and current change, keeping the power constant.
 
What I am guessing in 'cut-coil transformer' is that the primary 'cut-coil' produces strong magnetic field consuming lesser power due to reduced resistance.   When this strong magnetic field varies with respect to secondary,  the secondary should produce stronger power output than the input keeping the magnetic field same. 
 
We are just getting the difference between input power required to produce strong magnetic field and output power produced by the strong magnetic field.   
 
Think that you have a superconductor primary coil and normal secondary coil. If you just create "ON" and "OFF" of primary coil,  the secondary goes on producing AC wave perpetually and current in the primary is not lost because it is superconducting. 

Just a guess.  Correct me if I am wrong.

Trying to wrap my head around Vineet's "coil."  Are we looking at what is essentially a number of wires with their own capacitance, arranged in parallel, then dumping into a single strand back to the negative?  While current would be distributed between parallel wires, the voltage would be equal in each wire.  In this way, are we looking at a kind of step-up transformer?
 
If we put a high inductance, low resistance choke (many turns, heavy gauge wire?), are we not - subsequent to the "coil" - stepping up the amperage?
Just thinking out loud here, trying to understand possibilities...
Bob
 
Edit:  Interesting video that might shed some light on Vineet's "coil":
