Re: 1500-3000 turn coils
For your question, if I understand Mark, he speak of a ratio 10 unit of length
to one unit of diameter and from what I know the best ratio for a tesla is 5/1,
the bipolar is just 2 coil joint by the base and sharing the primary.
>From what I know again the big problem with bipolar is coupling, often over
coupling, it 's not easy as for a regular coil to change it ( you can't
secondary you need to increases the distance between the inner turn of the
primary and the secondary or split your secondary in 2 and move apart the 2
) Many people use a solenoid primary and have arc between primary and
secondary. I could understand your misadventures.
Sooo much to learn .... From your previous post I note: you already know a lot
and any way we all have a lot to learn that's why we are on this list.
Have fun with your projects.
