Some bifilars have adjacent coils in which the convolutions are arranged so that the potential difference is magnified (i.e., the current flows in same parallel direction). The magnetic field created by one winding is multiplied with that created by the other, resulting in a greater net magnetic field. Others are wound so that the current flows in opposite directions. The magnetic field created by one winding is therefore equal and opposite to that created by the other, resulting in a net magnetic field of zero (i.e., neutralizing any negative effects in the coil). In electrical terms, this means that the self-inductance of the coil is zero.

thanks Bill

I  have a clearer  understanding of  self inductance now .......and hopefully  a bit more understanding of  how to
connect my  pancakes

The only thing to add here is the interesting little experiment , which I haven't completed because all this winding is hurting, which involves checking out the difference in a coil with a copper wire whose copper is thinner than the adjacent iron wire. and vice-versa.

I thought of this experiment the day I noticed the drawing in the patent that NS relies so heavily upon, shows the copper including its wrapping to be exactly the same diameter as the iron.

Anyway, in a preliminary way, I will say that the one that has the thinner copper, thicker iron gives out much much more power than the one that is wrapped the opposite way. - That is both volts and amps.

The one I have not finished is one where both wires are the same thickness as each other. It is the control using the thicker wire for both. I only have the last iron wire row to complete. (Chad's way of wrapping ).

Now, I am going out to take today's measurements. etc....

@jeanna & Bill

I guess i was under the impression this thread was for speculations on the base station transmitter the second device in the patent, thats what you and bill said when you made it.  Moral of the story is this .. If you guys want to continue here without me thats cool but its kinda shady to take all the work we have thus far and tell me your starting a thread for specualtions on the second device when in essence folks are dicussing the earth battery .. Might be nice if you folks kept the dicussion on the earth battery in my thread and the base station transmitter specualtions in here since we dont know how that works yet.   Again if im way out of line i really will stop posting , its just sad to have gotten this far and have it now split.

Hi peaple,

You might find these threads interesting,

Cliff,

interesting   threads  argona   I can see that I am going to have to put  making a tesla coil on my list of stuff to do .

The  radioactive decay stuff  is  something I don;t think I want to play with though .

@ Joe:

I can't understand how you would be under the impression that this topic was for the transmitter coils?  The title of the topic....Stubblefield coils (bifilar) and speculations sounds pretty clear to me.

I take personal offense at your word "Shady" to describe me starting another related topic because you were very mean to more than several folks on your topic.  I did this to help you.  I did this to allow free thought and speculations, hence the title of the topic.  I thought this was what you wanted.  I did not tell anyone to post here, or to not post on your topic.  I would not do that.  People have free will and will post where they please.

You drove some pretty hardworking experimenters away from the earth battery topic.  I didn't say anything then as it was your topic and not my place to do so.  If you don't, or won't believe me, go back and read when some folks left.  The folks I am speaking of are not here on this topic either.  To me, that is a shame.

I think you have a lot to offer and I have enjoyed working with you but, I also believe you need to work on your people skills a bit.  Whether you do or you don't is not up to me, it is up to you.

You told us to make another topic to discuss "speculations" and that is what I did.  How you could even think to call that action "shady" is beyond my understanding.  When you get a little older, maybe you will understand a bit more, then again, maybe not.

Bill
