The bifilar pancake coil at its resonant frequency

Hi Itsu,

Probably the big size (volume) of the variable capacitors and the wiring associated with it establishes inherent (capacitive) coupling by default between the two tuned circuits.
Small sized variable capacitors like the ones used in AM pocket radio receivers might behave more favorably. Sorry. 
The unwanted coupling is what I think may now be happening but you maybe cannot remedy this easily and maybe there is no need to do so. 

Regarding the LED is not lit: maybe using a normal load resistor (across the pick up coil) from 10 to say 200 Ohm (just guessing) or a low current wheat lamp would also indicate whether its presence reflect back to the primary coil when the latter is the measurement setup in series with the 10 Ohm. 

Thanks for the video and for doing these tests.

Hi Gyula,

yes i figured that the chunky caps and cliplead wiring would be the cause of the coupling on that distance.

I will do some extra tests to get the led lit as it was lit when using my earlier used pickup coil (coiled up wires).


Thanks,   Itsu

Thanks Itsu!

Yes just ignore it in that way you head will not get any "junk" by me . Way you systematically try talk not only by you by the others  ?
Did you think others are not able to decide what is good or not ?  seems not .

Are you claiming OU or anything special when you light up your 100-watt 230-volt light bulb with your Tesla series bifilar pancake coil transformer?  Yes or no?

I am pretty sure that the answer is no.  Therefore the fact that you lit the bulb up is pointless, it does not demonstrate anything special about the Tesla series bifilar pancake coil.  There are better ways to make a transformer.  Therefore my questions still stand.

What is the Tesla series bifilar pancake coil good for?  What can you do with it?

Don't get mad at me for asking the questions that all of us should be asking.

The bifilar can help power a large "Ferris Wheel" rotor with a pair of "Radus Magnetic Moon Boots" through "Impulse Magnetization".
