A coil have some characteristics that make it more inductive or more conductive... If we reduce the coil to a linear segment of wire we see that the more crossection of copper the greater will be the conduction and lower the voltage drop for dc...
A capacitor should have zero field outside, thats because the positive and negative charges are alligned in two planes and so between the plates the field sum and out they subtract...
The greater is the dielectric the higher will be the charge for the same voltage...
Now how this apply to a coil?
How do we design a coil to have the most electric charge on its end points for the same voltage applied to it?
If we add a magnetic material to the coil it increase the inductance... This increase the energy the coil would carrie for the same amps flow. However like a capacitor it would need more charge to make the same energy... The lower is a capacitor the higher will be the energy per unity of charge.. A coil reversely will have more energy if more amps flow and the lower the inductance more amps can flow.
To create the high fields we need for stimulating water cell resonance only with fields wr are going to need a resonant tank to be able to have the coils to be polarized with real energy not only the flux... I think the amps are important. Var
I guess if the amps are not flowing the voltage alone wont do much....
So here it goes...
How do we design a coil to have most of its electric field useable and not only closing in itself like a capacitor?
My first guess is that it must have the ends of the coil far from each other
The coil former must be thick isolation or even air or vaccum, oil etc
The thickness of the wire seems to be important to make the coil work cold...
....
The coil terminations must go into water and must not have other ways for electric field to cut ways
The resistance or capacitancr that may close the resonant tank forms a voltage drop allong the circuit this will restrict the amps and at the same time make the cois termination to have the electric field according with the current flowing...
