@Conradelektro,

Quote from Conradelektro:

"I will try to measure the "increased magnetic fieldstrength" 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".


You may as well forget about even trying this experiment if you're unwilling to adhere strictly to the test spefications. I made that nail experiment video and got it to work. I'm all for testing. There were other failed tests made with "zinc screws" for magnet cores. It's important that one follow the instructions to get the results. Tesla-Coil-Builder calls specifically for two 16 penny soft iron nails, not just any kind of iron nails you may find lying around in your junk drawer! This may take a trip to the hardware store, and you should test the nails with a magnet to make sure they're the proper material. He says nothing anywhere about using 10 mm diameter Ferrite rods for coil cores. You would need a complex formula to determine the amount of wire to wrap them with!

I built and tested dozens of these Tesla bifilar coils. I do more then just throw words around. I achieved the overunity results I'm claiming. The nail test alone is two times overunity. Good luck, and Merry Christmas!

@Conradelektro,


I feel the experiment on increased magnetic field strength per watt should be conducted with the coreless spiral pancake as patented by Tesla. Two coils of the same diameter, one single wire and the other serial bifilar. Your signal generator and micro scale would give the test a high degree of scientific validity. I suggest measuring iron filings by weight.


The problem of substituting a high permeability core of low remanence for the soft iron core is very complex, and out of order for a coil that was patented as a flat spiral pancake with no core in the first place. Comparing the different types of pancakes would be a very worthwhile undertaking, and put this issue to rest once and for all.

Here's a couple of snapshots: 


On the top, the materials for the Cook battery: Conduit, 16 and 32 gauge wire and welding rod cores.

Next, one of the 4 coupled 1/2" X 1" diametric tube magnets stacked for the magnet core and their bifilar output coil.

@synchro1: in one of your posts you cited  this page http://my.voyager.net/~jrrandall/CookCoil.htm . On the bottom of the page one finds a update http://my.voyager.net/~jrrandall/CookUpDate.htm which says:

Oct 2001 -
- I can NOT make this device work. That does not mean that it never worked.
- The device, AS I BUILT IT, does not work.
- I can not say whether it might work if built to different dimensions or specifications.

In which way do you try to overcome the shortcomings of the 2001 Cook Coil design?

Are the four "tube magnets" on the photo axially or diametrically magnetized? If they are diametrically magnetized you should rather build a magnet spinner to prove the OU effect of the "synchro coil".

Good idea to try flat pancake coils without core (one mono-filar the other bifilar), I want them anyway for tests with the magnet spinner.

I was thinking about the "nail core", which introduces many unknown factors, e.g. the iron used for manufacturing the nails. The core-less pancake coils are much more well defined.

Winding the pancake coils between two sheets of thin plexi glass should be simple. The plexi glass should not influence the magnetic field much?
