Tesla's "COIL FOR ELECTRO-MAGNETS".

[Farmhand]

Hi Gyula, I get you on the AV plug I think.  So if I may could I ask a couple of questions please. Would it be true to say that with the plug and capacitor there is a second instance of displacement current ? The first instance between the capacitor plates and the second instance in series with that capacitor's plates and whatever it can go to, maybe a tin plate or the bench or the ground/air ect. ? And if yes that the quality and value of the second capacitive coupling will give the AV plug it performance in a specific situation ? The plug uses the second displacement current path for the return ?

I think that would be the principal of the receiving of the wireless power transmission of Tesla's last patent. The displacement current path might be possible from the top of the tower's air capacitance to the Earth and the sending Plant's transformer is connected to both as well. There is just no diodes, resonant coils do it all.

Cheers

Doesn't an AV plug work like the drawing shows or similar ? If yes than the AV plug is really just half of a FWBR.  Nooooooo darn I think I drew the currents flowing the wrong way hahahaha  but I think you can see what I mean.

I think Tesla describes the effect in his high frequency lectures, he knew what was happening. And that he could use it.

I think if we had say a 1/4 wavelength of say 100 meters then if we place a resonant receiver coil there it would get maximum excitement, but if we place it at 3 x 1/4 wavelengths the wave would be more attenuated or down graded. He may have over estimated the efficiency of doing that at HF though 35 kHz max he said for transmitting at distance through the ground so as to avoid too much degradation of the current waves.

Does displacement current flow in EM waves ?

For the AV plug you are correct.  The key factors are the frequency of the AC signal in the single wire, the amplitude, and how much capacitive coupling the power source has to ground and the charging capacitor has to ground.  For every rising edge of the AC source, a tiny "puff" of charge passes through the forward diode to charge the cap.  For every falling edge, a tiny puff of charge flows through the reverse diode and that also charges the cap.  The tiny puff of moving charge though the diode is the displacement current.  It's the same current that is capacitively coupled to ground at both the source and destination ends of the current flow.  It's a two-wire charging system that only has one physical wire.

Sometimes you can have a an audible high-frequency oscillator on your bench and by bringing your hand near to it you can make the pitch change. Same idea, the capacitive effect of your hand in proximity to the oscillator will cause very faint displacement currents and affect the oscillator.

The higher the frequency and the higher the amplitude of the signal the larger and more frequent the puffs are and the faster the capacitor charges.  The stray coupling capacitance to ground will act like any capacitor and conduct AC more readily the higher the frequency.

Well, you have to understand. We were doing the nail experiment as it was described. It did not work. So in reality your experiment has added ingredients as compared to the 'experiment' from the web page.

But if there is something missing, I would be happy to see it.

Is your nail ending up permanently magnetized in the process of kicking it with HV? That is the first thing that comes to mind of what might happen.

Looking forward to the vid.  Before you stated  the use of KV, I thought you meant precharging the bifi like below.

A capacitor discharge would charge the coil well too. The final coil voltage is a function of the wraps. I just finished the video. I detected a noticeable amount of magnetic remnance in the SBC core, so I connected the nail heads untill the core attractions equalized. The experiment again demonstrated the 2x SBC magnetic force as before. I'll start uploading the video soon!

Tinselkoala could run the paper clip test experiment on his two kinds of coreless pancake coils, and help factor any magnetic core remnance issue out entirely.

I restored my laptop and plan to video tape and upload the experiment for you to let you decide what to make of it. The SBC stores it's pico farad capacitance in kilovolts and nano amps. A 100 turn SBC has 250,000 times the voltage potential between the wraps as a single wire coil. How do you imagine this power gets into the coil if it's not sent there? The high voltage spike from the magnetic field collapse charges the SBC to full potential. This happens automatically when the coil's pulsed, but you need at least one strong field collapse to generate the high voltage that's stored in the bifilar windings. The collapse dosen't effect the single wire coil because it lacks the storage potential. This high voltage storage capacitance eliminates reactance to current direction change in the coil windings, and generates double the field strength from the resulting Lorentz force. I got the experiment to work. You're asking me why yours caused trouble. Please put your thinking cap on!

Electrons are attracted to one another as they pass head on. There's no influence between them on the perpendicular. The head on electrons turn when there's no reactance to direction change from the high bifilar windings potential. Imagine two electrons orbiting each other. What happens? Think about it!

I can suggest a good test for you.  If you have a compass and arrange your setup so the regular coil and SBC will try to deviate the compass from magnetic North you can then measure the relative strength of the fields from the two types of coils at different compass positions.  Say the compass is a foot away from the regular coil and when you energize the coil it deflects 30 degrees.  Now try the same thing with the SBC and see if the compass also deflects by 30 degrees.  This test will be much more accurate than picking up paperclips.

I will remind you that you need to know the current through the coils.  So you measure the DC resistance of the coil and then measure the voltage across the coil when you connect the battery.  You might not know if the battery is freshly charged or nearly discharged.  That will affect the battery voltage under load so you must read the voltage and then calculate the current.  Alternatively you can use your multimeter to measure current.  One way or the other, assuming that you are comparing two coils with the same number of turns and the same core material, you have to measure both setups and be sure the current through both types of coils will be the same when you do the tests.  You should present that data as part of your test results to your audience.

Looking forward to seeing your clip.  We can see if there is any evidence of very high voltage.
