Massive Coil: How To Measure Inductance and capacitance & Self Resonance Frequency. (SRF) 

Thanks buddy. I've been trying a bunch of these methods with some different am coils recently and I'm really excited to see yours

Gr8T! I am so glad Jeremy told me about you. RIGHT ON.

Yay..looking forward to watching this later

Cool. The art of measurement is a truly beautiful thing. I Love it because when done properly it is pure, unbiased. The art of measurement is the art of truth. Peace Russ.

Great! Liked it.

I would have attacked it a little differently. I would have excited the coil with another coil driven by the signal generator using a sinewave. Put the scope on the test coil and watch for the peak as you change frequency. Then alter the frequency until you get the highest peak, this should be OK to find, I calculate SRF Q at 62. I'm sure you know you want to couple in energy but you want the drive coil to have as little affect on the test coil as possible, I would try 3 turns about 3ft in diameter around the test coil. (might add a 50 ohm resistor to protect you signal generator from driving a a low impedance coil.) Adjust coil size and/or drive as needed. I expect it will be close to your 114 hertz, Remember you added 15pf scope probe capacitance. Assuming a 10X probe, if you can reduce that capacitance, even better. Now the interesting part, there is a program that will calculate the Coil Self-Capacitance and the inductance using the Least Squares Method. electronbunker.ca/Extras/Downloads/LoopSelfCap_r1c.ods OR electronbunker.ca/Extras/Downloads/LoopSelfCap_r1c.xls You use the extra capacitors as you did, to find the Resonant Frequency peak and record those capacitance's and frequencies. You can enter up to 8 (best accuracy) but can use fewer. Then using the program, you enter the resonant frequency with each capacitor and the capacitance of that capacitor. (do not include your measured coil self capacitance, the program will calculate that, (you might add the scope probe capacitance) It outputs the Self-Capacitance and the Inductance along with many other things including a deviation graph. Very cool program.

I measured firstly resonant frequency.I used for it SDR radio.I connected one wire to receiver input and an another wire to a short thin wire (it played role of an antenna). To find a resonance I used a piece of ferrite road. The inductance we can measure by RLC meter. To find capacitance when we know inductance and frequency we can use online calculators.

Using inverse Laplace transform and your calculated values for voltage, inductance, capacitance and resistance, I came up with a frequency value of 114 Hz (using Desmos graphing calculator)

The most satisfying way to det SRF , {personally} for me on a reasonably high Q large inductor is to use a 0 offset square pulse, with a say 10M ohm resistor ahead in circuit to the F generator, then slowly lower the F until the square wave at the junction between the R and the inductor goes from non readable to a saw wave then finally a beautiful sine at 0 phase angle. There’s something about watching a square pulse turn into a perfect Sine.

I am a beginner. Please explain why you are measuring at a frequency that is 45 degrees phase.

Just hook it to scope have freq gen slowly sweep they frequency and watch for greatest amplitude that is you’re resonant frequency check multiples for that frequency to see if they are greater or less

Your clock is not running, lol, great vid thumbs up !

thanks

The battery in his clock needs replacement ;-)

You may use Ut = U0 * e^(t/RC) instead of the time constant.

What do you mean, pull it out, in parallel mode, do you need to hit it with 2 differant inverters, Paul Babcock would be proud. WHAT do you mean, "pulsed in time w earth" do you think someone could, use a small generator to run an alternator generator, and unground it to itself, pass that line into a medium size transformer, the primary, and have at the end of the primary an switching circuit that 'll la it to ground, and that this would produce transient spikes at whatever the flux to earth rate is, at the rate of the pulsing switch?

What is the reactance with scalar waves

Remember your other video sates the capacitance is in the enamel on the wire; the magnetics maybe from the wire and tha AC skin effect in wires

Great video man, usually this type of videos are not in RU-vid, I mean, not with this explanations or details. What happens with the work of Stanley Meyer? I'm actually working in a replica of his work an your work was very useful for me to do that replica but I don't understand all the details, because I have problems with the coils of the particle accelerator, so this video is much more useful for that purpose. Thanks again!. Sorry for my bad English :).

the coil you're holding is the smaller one?

Russ, Why didn't you do a simple parallel resonate circuit? Measure the ac current until it drops to almost zero, that would show resonance. Then you would have your frequency and be able to accurately calculate your inductance. Use the sweep function on your function generator, assuming you have a sweep function, pretty sure you do with your new Tek scope.

I expected more capacity than just 400 to 500 pF

You will get better results in calculation if instead of Pi you use 20*sqrt(2)/9. Pi constant is incorrect, see proof in Danny Wilten videos about that.

According my theories on magnetism and electricity, the reason a coil has more energy than the energy you put into it with a magnet as it sweeps by and then collapses its field is because in my theory, a magnetic field is a toroid with electrons orbiting in it. Electron orbitals are not as spherical as they are seen in science books. In fact, the elite schools teach that electron orbitals are like cotton candy cones at the positive areas of an atomic core. Anyway, in some metals, like Iron, there is a predisposition for iron to crystalize, when slowly cooled after being heated and aligned to the north and south pole, into a grid where so many of their neutrons in the iron are parallel with each other, and the aether or quark fields also align and increase pressure of the quark field inside the metal, most of it hitting the boundary layer between metal skin and the air and reflecting back to a precise center, depending on the shape of the metal. This is why when you add a magnet to another magnet, the center line of the magnet can move up to be exactly between both magnets, or close to it. Or when steel is put on a magnet and the magnet center moves down toward the steel, it is because the magnetic waves in the quark field are rebounding at the wave boundary area, the skin, with a similar material, and thus pass part of the way through, turning the steel into a partial magnet, or combining with the pressure waves in the other magnet attached to it. As a magnetic material gets stronger and stronger, it forms electron orbitals not around the nucleus of the atom, but around a group of atoms. I call them intramolecular electron orbitals. I thought I had invented that term and concept, two years ago, but it turns out some people in some universities got the same idea, about intramolecular electron orbitals, not about magnetism coming from neutrons. Anyway, as a magnet gets stronger, the toroids inside and around that center neutron get stronger, until enough of the material is aligned, and the pressure waves of the toroids on the neutron escapes outside the metal and forms weak electron orbitals along the toroids of quarks. Kind of like invisible donuts with a tiny one in the center and bigger and bigger donuts added until they can be felt outside the magnet. Electricity also creates magnetic fields, not because the atoms are already aligned, but because the material's neutrons and intramolecular orbitals that already existed in the conductive metal begins to shift and align with the spinning electron field on the skin and inner skin of the wire. So a wire becomes a pearl of north and south poled magnets the size of tiny groups of atoms, pressurizing their toroids until they form those big invisible donuts again on the outside of the wire, in nodes or clusters of nodes, just as Tesla discovered not so long ago. Because the toroids are made of quarks or q particles as I used to call them, they pick up the free quarks in the air outside of the coil. When the circuit of the coil is opened and shut off, and begins to collapse, the inner layer drains, creating a negative charge, and the toroid donuts begin to shrink, but they don't lose their quarks by dissipating them back into the air like a cloud, instead, the quarks are pulled in by the electron orbitals until they are part of the intramolecular orbitals. When your coil sings, or resonates between positive and negative as it collapses, perhaps with each toroid, as each toroid collapses, it allows the next doughnut to shrink down, one at a time, just like Joseph pointed out, at the top of a magnetic toroid is a bump on each side, and therefore a negative and positive-positive negative bump. It is likely that the current coming from a collapsing coil is experiencing the influx of both sides of the toroid, the negative outside and positive inside as it moves into the coil's outer layer/skin. What this means is that a collapsing coil is basically a quark pump, expanding into the air when charged, locking quarks into growing toroids, and when discharged, dragging those quarks back into the center of the coil, adding more energy than was given to it. To gain energy from this you would need to ensure that the quark field toroids were not collapsing into any metal under the coil or nearby. Also, the angle of your magnets would have to be pulsing through the coil so as to not add core reversals within the first sweep, which I believe you worked on, distance from the coil and such, and speed of the reversal. If the magnets are spinning too fast, you do not give the coil enough time to discharge fully, or form the toroids fully. I noticed that Joseph had a very large magnet in his video, and a very slow spin speed. I think your greatest problem is the type of magnet you are using. I learned recently that old type magnets had less guass, but larger toroidal fields, whereas the new neodymium magnets have higher guass levels but shorter and squater magnetic fields. In other words, the cheaper, older style magnet would probably work better because the bigger but weaker magnetic field goes deeper into the coil to the other side.

I'm thinking that lrc meter, is a men in black, peice of crap plant.
