this to me smells like 'step charging' the flux density.
inductors, like capacitors don't reach stationary charge instantly.

this is good thinking.....but the flux has a much much easier time building up it's "charge" then a capacitor......the inductors magnetic field is created very very quickly......this is why stan can use frequencies such as 5khz pulses which can be doubled......that means that the inductor charges so fast that it can create an equal pulse on the off pulse of 5,000 pulses a second at a 50% duty cycle....a capcitor cannot charge to full energy with one pulse out of 5,000 unipolar pulses...it needs many to achieve the level do to the dialetric material and spacing......and remember we are not using XL=XC.....we are using XL>XC.

exactly donald.

teslas patent clearly states this.


i would just control F (search) "step charging" in teh tech brief and read those sections.

you are confusng the concepts.

read teslas patent on bifilar inductors....it states exactly what you quoted.

a bifilar coil simply increase the magnetic field strength much more then a normal inductor would due to it's distributed capcitance between wires which allows higher energy storage...aka larger magnetic field so the more turns of bifilar wire there are each one is basically compounded on one another like mini capacitors going -+-+-+-+-+ then it will have a greater inductance then a normal single wound coil......this is why meyers says over and over again if you want to increase the votlage potential going into the cell just add more turns to the resonant charging choke....they are directly related.

teslas patent explains it quite well.

Ok lets imagine that the coil does work like you think , the winding is wring .

The coil shorts out too easily , thats a problem , so that meant this was wound in sequential order , not bifilar .

it did not short out easily.....it shorted out when i applied over 150 volts amplitude at the primary.....jolt's shorted out instantly.

did you short your vic coil?

ouch :(

yes then i successfully rewound it.

but then the beginning end of the secondary snapped to short to reconnect it......and that was unfixable in my current supply of wire.

when you are working with hair thin wires it is a huge pain.

so forcing huge amounts of voltage amplitude into the primary is a no no.

and seeing that i do everything by hand with a stainless steel tube..2 toilet paper rolls....2 coffee mugs.....and counting everytime i see a red mark come around......tends to get tiring.

well it's good to know that you should not input more then 100 volts amplitude into the primary...

aye, best to stay in the 0 to 12 volt range i guess? is there much advantage to going past 14 volts? since you would not get that in a car...

i would say 26 volts at most.....but i think around 40 votls would also be beneficial since gas production is directly related voltage amplitude.

differences aside if found this thread very informative.
Thanks,
