Tesla's "COIL FOR ELECTRO-MAGNETS".

Shumann resonance is merely one aspect of the "Oscillating frequency of magnetisem" as measured along any Bloch wall and determined to be a constant.

You should win some kind of prize for that statement.

Synchro1:

The SBC resonant frequency Farmhand measured in his SBC electromagnet  is the same as his other Tesla coils, determined by the constant L C frequency in all the SBC coils. This is the same harmonic as the frequency between the Earth's magnetic poles and also the poles of a permanent magnet, in proportion to strength. The SBC's all share the same capacity to inductace ratio. The pure sine wave resonance is in tune with a broader spectrum of harmonics, including the one inside the neo sphere, depending on strength.   

Matching a proper size and strength sphere magnet spinner to an SBC for resonance is important

You seem to be saying that all SBC coils will have the same resonant frequency.  Don't forget that L and C can change from coil to coil.  So coils can self-resonae at essentially any frequency.

Your comment about the sine wave resonance is strange to say the least.

@MH: Isn't the Schumann cavity formed by the Earth and the Ionosphere? Hence, not thousands of miles out in space but rather only about 80-100, (or 50-300 for the extreme range) and varying with sunlight pressure (and HAARP activity of course.)

Lightning discharges are the equivalent of dielectric "punctures" in a capacitor. Fortunately the atmosphere heals, like a good poly film cap. Tesla's idea was to use this big capacitor to transfer inputted energy wirelessly to any point within the cavity, and also, using similar apparatus, to extract or entrain some of the vast amount of energy that is already stored there, a tiny bit of which we see when the dielectric punctures in a thunderstorm. It's my unreasoned faith that this might somehow be possible. It is my fair certainty that it will involve physically very large apparatus and high initial energy inputs.

@TK,

Thank you! I'm up for the "Dumbell" science award again.

My "Zither of Unity" monopole SBC spiral self runner is powering the 1/2" magnet sphere in excess of the transister switch speed in the self loop video. This has to be a result of oscillatory SBC resonance. The tiny thread spool SBC up and begins to run itself too, with no output coil loop at subsonic r.p.m.

I believe that the SBC basically begins to power the magnet spinner with  RADIO WAVES at high frequency.

@Farmhand:
When I'm determining resonance of a coil or tank, I generally use a "sniffer" coil made from a turn or two of wire, looped around the coil I'm stimulating, and I probe this loop with a scope probe. Using a square wave excitation from the signal generator is proper, as the probe coil will respond sinusoidally when you find the resonant frequency. Once you've found the frequency switch to sine excitation for very fine tuning to peak output from the probe coil. If you are working with a TC primary-secondary pair or just the secondary, you can stimulate the primary directly with the FG and a 50R in series, and probe across the secondary with a 10 meg resistor in series with your scope probe. Again, square wave stimulation will result in the highest amplitude sine wave on the secondary or probe coil output, as the induced EMF is proportional to the rate of change of the inducing current.
