A hi-voltage spike does work through Tesla's SBC magnetizing ferrite. The spike fails to have any such effect on the ferrite core of a single wire coil. Perhaps if I demonstrate this difference it will lay to rest the false assertion that the coil types share no difference?

     "Ferrite magnets can be magnetized with shorter pulses, with a width duration of a few microseconds".

                                           This pulse needs to pass through a hi voltage SBC.
 

 "Magnetic fields are produced by electric currents. The large amount of magnetic field required to magnetize permanent magnets requires the current to be in the range of 10 to 30 kiloamperes. To provide a safe and reliable method to avoid overheating and fusing the current carrying conductors during magnetization, an extremely fast current pulse is required. A fast pulse is the preferred method for magnetization. Magnetic materials reacts quickly to the applied field; however, care must be taken to limit eddy currents effects created in conductive materials by the fast rise time of the current pulse, toavoid any shielding effects. Pulses width duration in the order of 1 milliseconds are considered ‘long’ enough for the magnetization process to be successful. Ferrite magnets can be magnetized with shorter pulses, with a width duration of a few microseconds".

10.2.2 Capacitor Discharge Magnetizers Capacitor discharge magnetizers employ capacitor banks that are charged, and then discharged through a coil.
 
                 Tesla's bifilar pancake for electromagnets more aptly may have been named:

                                          "Capacitor Discharge Magnetizer Coil".

Syncro1:

We had a discussion about scrap yard magnets.  I also have given you all of the background and links on how a magnetic field is generated by a coil of wire.  So you saw a scrap yard magnet up close and saw the configuration was a series bifilar coil.  So apparently you went, "Eureka!," it's Tesla's design and there must be something special about that design!

Like I explained to you with logic and references, there will be no significant differences in the magnetic field generated when you compare the two coils.  That's not "ridiculing."  Tests were done by some of the people around here and they confirmed the expected results.

To me it looks like you are excited by all of this stuff and you are making leaps of logic and faith in your excitement.  Let's assume that they want an even-strength magnetic field across the disk.  So a spiral coil will do that.  If it is in series bifilar configuration, we don't really know why they did that.  It could be for manufacturability or for better heat dissipation, as some examples.  However, certainly it was not done because of any special properties of an SBC like the way you are suggesting.

Same thing with the Leedskalnin PMH.  The PMH requires that the two pieces you are going to stick together have flat shiny surfaces that will mate perfectly together.  If you are an "enthusiast" you should look it up.  So this effect will never happen in a junk yard setting.  So you can see that's an example where you made an incorrect leap of faith.

I have a pretty decent knowledge level about this stuff.  Feel free to ask me a question if you want.  This is not "World of Warcraft - Special Nerd Edition," this is a place to chat about circuits and exchange ideas and be real.

@Milehigh,
                 You are really stupid. You're the one that needs to test the bifilar experiment for yourself to see how the SBC works as  a "Hi-voltage jolt magnetizer". This experiment is too easy to replicate. Take a trip to a scrapyard for yourself where you'll find a large capacitor inside,  not a rats nest of ampere turns like you pretend. Why don't you  knock it off man?

Synchro1:

Who says that a "high-voltage jolt magnetizer" works with an SBC?  Do you have a reference or link for that or are you just projecting your SBC wishes and fantasies onto these systems?

Assuming that there is a capacitor inside a junk yard electromagnet, why do you think it is there?  Do you have a theory?

Bifilar vs single wrap nail magnet test:

http://www.youtube.com/watch?v=9mxtwS2OsaA&feature=youtu.be


It's a trick! The joke's on you. The bifliar can store the high voltage from the collapse spike, and create a permanent magnet, but it passes right through the single wire coil.

Synchro1:

You know that when you disconnect the current-carrying wire from an SBC you get the high voltage spike.  That's actually the first spike in a series of spikes.  It's the ring-down as the self-resonating coil dissipates the stored energy.

The ring-down in the coil like that is what they could use to demagnetize ferromagnetic materials.  So I suggest that you do some surfing and think about your setup some more.

I am not necessarily saying that's what is happening in your setup, I am referring to the general architecture of a magnetizing system.

I have mentioned to you to use small pieces of test loads for the electromagnets, either using small nuts like I showed in my repeated test or just cut up some paper clips into 2 or max 3 mm long pieces. The reason I ask you to use small pieces of test loads is that your electromagnets seems to be also weak like my electromagnets were and the touching areas between the bolt and the clip surfaces are very small. I felt uncertainty during my tests with the clips but I was fully certain with the small nuts. The clips were too heavy for the strength of my electromagnets, and I can see the same behaviour from your electromagnets.

What is battery voltage by the way when you connect any one of the electromagnets? Would you measure it?

Apparently, you still don't get it. The SBC nail core continues to pick up the two clips up even with the power disconnected. The core is completely magnetized. The best way to magnetize is by sudden shock. The bifilar throws a bigger spark. The single wire coil won't work as well as a magnetizer. You retry the experiment.

Indeed I did not see from your video that the current to the SBC electromagnet was disconnected. Then this is comparing apple to oranges, this is not a proof for the SBC at all.  The test is not about to make permanent magnets from nails but compare two kind of coils with nail cores. Magluvin or myself did not make permanent magnetization to the nails or bolts, it is pointless to saturate an electromagnet's core. 

And please answer my question when any of your electromagnets are connected to the battery what is the loaded voltage across the battery?

It is not rule of course.   I am 'amazed' by your question I feel when I read Winnie-the-Pooh.  Who told you to make a permanent magnet from the nail? 

IT was YOU who referred to this link http://www.tesla-coil-builder.com/bifilar_electromagnet.htm and please show where David Thomson wrote you have to make a permanent magnet from the nail to lift up the paper clips? 

What is the point in making a permanent magnet from an electromagnet in this test? To lift up objects an electromagnet needs a DC current and the aim is to check any difference between a single wire and the bifilar wire coil provided the two cores have similar (ideally identical) ferromagnetic properties.  The same amount of DC current should be used for both coils while lifting up the objects.

Of course you can make a permanent magnet from a suitable ferromagnetic core and you do this by inserting this core into a coil and switch a big enough current into the coil.  But David Thomson did not write to do the test like making a permanent magnet first and then lift the paper clips with the nails.

Please repeat your test with new nails that are not magnetized yet, please cut up the paper clips into small pieces and do some several runs like I did here: http://www.overunity.com/11350/confirming-the-delayed-lenz-effect/msg357952/#msg357952

@Gyulasum,

                    Tesla's Serial Bifilar Pancake coil for electromagnets, is a "Capacative Discharge Magnetizer Coil". That's the end of the story. Just accept it! It won't help for me to cut paper clips up, or measure d.c. current. Jonathan Livingston Seagull thought he was somthing else too.

                     I knew how Tesla's bifilar coil worked the entire time. It's the "Scrap Yard Magnet"! You guys imagine your group of superstitous Hotentots are valuable dehoaxing "Myth Busters"  right? You guys look really, really stupid to me. Wake up, and stop causing trouble. All you labyrinthine Cretans have done is insult and degrade Nicola Tesla, an unparalleled genius!. There's gotta be a hampster hidden someplace!

                    The nail test is just a "PARLOR TRICK" to demonstrate the SBC's real power! Try and get over it. He made a monkey out of you.
 
                    I'm not the person who tricked anyone. I scolded Milehigh for his outraegous assertions on the "Lenz Delay" thread about the no difference between the coil windings. I've been trying hard to explain and distinguish this coil application throughout the entire course of this thread.

You have really dug yourself into a hole.  Why should anybody take you seriously?

You are very close to becoming the new "Innovation_Station," with a very low signal to noise ratio in your postings.  The performance is getting stale and the greasepaint is running.

Myself and Gyula genuinely tried to help you but it's pretty obvious that it's futile.

@Milehigh,

                  You're petrified wood! Tesla's bifilar pancake coil for electromagnets is an:
 
                                                          "IMPULSE MAGNETIZER COIL"! 
 
                   D.C. current has no special effect on this coil unless it's powerfully pulsed. You guys don't really believe "Tesla Coil Builder" designed his electromagnet nail core test to fail, do you? His experiment is just a puzzle type teaching tool. The single wire coil won't play the same trick, and therein is the critical difference between the coil types.
 
Here's a Leedskalnin coil shorting video, similar effect:

 http://www.youtube.com/watch?v=6lspAxYGxWA
 
The Leedskalnin horseshoe output coil shares "Impulse Magnetization" power with the SBC. Lorentz force and quanta level power may help explain the extra propulsion..
