I haven't had a chance to map the fields like you requested, 0c, but here is a video of a comparison I did that might be of interest.

Good stuff. And I'm sure there's more of this to come. I know how much you like those HV sparks.

But please don't forget I'm primarily interested in the low voltage DC or transient DC magnetic characteristics. First thing I'd like to find out is if there is a noticable difference in shape or intensity of the magnetic field that might make a bifilar coil more suitable for use with a magnet motor. And how effective is a ferromagnetic core for concentrating the magnetic field with these types of coils?

@ Tinsel:

Great video demonstration!!  I subscribed to your youtube channel.  I am on there as 0WildBill0.  Very nicely done.

@Oc,

In an alternator, the bifilar coil will give the same voltage but twice the current over a regular wound coil with the same length of wire. I just finished building an axial flux alternator with bifilar coils, my son-in-law tested both coil versions before I started winding my coils and that is what he saw as output under the same condition of testing.

The results with the bifilar coil Tinsel shows in his video was in line with what I was expecting to see.

Thanks TK for the nice video.

Take care,

Michel

Would you be able to share any photos, drawings, notes about this alternator you and your son-in-law built? There might be some answers there. I'm especially interested in the increased current you found (increased current = increased magnetic field).

The spark demo was interesting, but I was also not surprised. There have been a number of experiments demonstrating the electrical characteristics of a Tesla bifilar coil. Except for a couple obscure comments, I have been unable to locate any description of the magnetic characteristics.

@TK, Thanks again for another interesting and informative experiment. Keep up the good work!

@ Oc,

You can view the alternator in my Newman motor thread. The Newman uses bifilar and the alternator too. There are pictures and details there:

Nice work Michel. Maybe I should be asking you these questions?   :o

Have you checked the magnetic fields of the coils during alternator operation?

Just to be clear, there seem to be 2 types of "bifilar" coils that people use. The first, the Tesla bifilar (512340) has parallel, same direction current paths. The other type, that I will call the "Stubblefield" type (thanks Bill) has opposing current paths, hence cancelling mag fields.
It would be good for posters to specify which type they are discussing, just to be perfectly clear.
I and 0c are mostly concerned in this thread with the Tesla type. But I welcome all (relevant) comments.
Thanks...
TK

FYI: Wire wound resistors use something very similar to a Stubblefield coil to cancel out magnetic fields and reduce inductance.

The Stubblefield cell is not like the Tesla coil, the iron wire and copper wire are not connected together. They are wound side by side to increase the area of exchange in the electrolytic process. The iron wire and iron core are used to magnify the magnetic effect of the cell. Although called bifilar wound, they are indeed the anode and cathode of a battery in close proximity and far related to Tesla's own.

Take care,

Michel

Thanks, Michelinho. So we really have 4 types, then--the Tesla type, flat, single wire not non-inductively wound; the Stubblefield type, wound with dissimilar metals, maybe inductive maybe not, and the Bedini type, multiple windings maybe inductive maybe not, and the non-inductive wound resistors that 0c mentioned, definitely bifilar non-inductive.

Thank goodness I am only going to be looking at the first type, for now!!

I just finished winding another identical Tesla type flat bifilar to match the other one in the video. So I will try to do the same test as above with the two Tesla bifilars.

If I can stay awake long enough tonight.

I just remembered, there's also the cadeuceus coil. So there's 5 types. But I'm primarily concerned with the Tesla patented bifilar coil.  ;)

Hi TinselKoala,

Any update on the test unit?

Not much. I found enough wire to wind another identical Tesla bifilar, but not enough to wind another identical pancake.
So I made the bifilar, and tested the two bifilars together--they gave an intermediate spark.
I have not done any DC field mapping as per the original request from 0c. I'll be making a little gimballed magnet, sort of like a 3-d compass, to try to map the fields in a visually descriptive way, and I'm also building groundloop's MOSFET H-bridge circuit to act as an actuator for various experiments using these coils and also for ltseung's famous experiment001 and explain004.

@ TinselKoala:

When you do Tseung's infamous experiment 001, please be sure to do it correctly this time. (Ha ha)

Obviously, and I hope you know, I am only kidding.  I really don't know why you are wasting your time with the LOT as I thought all of your explanations and earlier tests were exactly correct.  The only problem was, it did not prove his theory.  I seriously doubt that there is any test in the universe that could do that.  Keep up your good work though, I am learning a lot from you.

@TK,

Just what do you mean by "intermediate spark"?

Have you been able to test the intensity of the magnetic field with DC or a short DC pulse? Is it any stronger with the bifilar coil?
