Synchro1:

Following up on your comments about magnetic field strength of a coil, it's all in the ampere-turns.  It was already discussed a long time ago.  A series bifilar and a regular coil with the same number of turns will generate approximately the same strength of magnetic field.  You can find it all proved in books and online and in YouTube clips.

Here is the real thing!

Note the formula for the magnetic field strength of a coil is B = u₀ni,  where n is the turn density per unit length of coil.

So the real way to get a stronger magnetic field from a coil is to increase the turn density and push higher current through it.  The way to do that is to make a coil that has many layers of turns one on top of the other.  You can buy a roll of speaker wire and you have an instant coil with many layers of turns one on top of the other.  If you buy a large spool of a small gauge wire and then put a good ferromagnetic core in the center you will have a very strong electromagnet.  You just have to increase the voltage to the coil to overcome the DC resistance of the wire.  You also have to monitor the temperature of a coil like that if you push it.  The inner layers of the coil are in their own semi isolated thermal environment and could get really really hot.

You note it has nothing to do with the regular or series bifilar coil configuration.  It's all in the turn density and the current flow.

@Tinselkoala,

Here's an excellent video on the "Law of Laplace":

http://www.youtube.com/watch?v=wvScSTbly1c&list=PL62433DB6D0A09218&index=17

This video demonstrates the effect of passing current through a magnetic field on a conductor. The Tesla bifilar neutralizes this effect; Hence there is "Zero reluctance to change in current direction", unlike the single conductor in this video. The strict engineering terms you requested of me can be simply stated as; "The Tesla series bifilar neutralizes Laplace's law"! The coil measures no inverse Henries.

                          The units for magnetic reluctance are inverse Henries, H–1.

Can anyone please try and explain to me why no one else on this web site can get this simple experiment to work right?

Have another look at this video:

I challenge anyone to competently demonstrate the presence of inverse henries or the absence of increased magnetic field strength in the Tesla series bifilar!

All Tesla's laboratory notes along with his original patents were confiscated by the United States Government, after Tesla's death. They were either censored or redacted then re-released to the public. Tesla's patent for his "Coil for Electromagnets" was one of the patents heavily censored and reworded. This coil is and always has been overunity the entire time. That's why no where in this patent for an electromagnet can anyone find any reference to electromagnetism. However, this patent was already purchased by Westinghouse, and appeared in scrap yards where the secret was closely guarded under watchful eyes! That's why there is hardly anything to be found about those kinds of electromagnets in the historical archives.

@Synchro1:

Bifilar Tesla coil is OU: How would you prove (by doing what kind of measurements) that a "bifilar Tesla coil" is "over unity"?

Bifilar Tesla coil and magnetism: Once I am back home near my lab I will try to measure the "increased magnetic field strength" of a bifilar winding over a soft iron core (nail) and over a Ferrite core (I have some 10 mm diameter Ferrite rods). I think I have all the materials needed and will do it more or less like in the video http://www.youtube.com/watch?v=9mxtwS2OsaA you mentioned, but with a laboratory power supply instead of a battery and an Ampere-meter to see the real DC power demand in both cases (100 windings mono-filar versus 50 windings bifilar). I have very good scales, (electronic letter scales) which can weigh 1/10 of a gram, to measure the pick up weight by both "electromagnets".

Synchro1 you are making some pretty strong statements. It would be better to back up these opinions by real experiments than by words. There is a lot of Tesla-lore and Tesla-hype out there repeated over and over again by people who never produce anything tangible. So, pointing to questionable sources it not of much help.

Let's do real experiments instead of throwing words around.
