It's not as complicated as it may seem...

A pulse into a coil creates and expanding magnetic field. How is this possible when the pulse has minimal current?

Think about that for a moment Grumps....you answered your own question.

If there is a changing current (and there is) then there will be a changing magnetic field. Why is it assumed that these fields need to be strong to start the process?

What I was getting at is that ether rolled back on itself, has a magnetic moment and is therefore inductive when in this form. You can only detect the little ring magnets of curled ether by interacting with them, which interrupts the ring pattern/shape.

setting the next test up today and will try to bring it all to fruition this weekend...

yes, and the RE field is not one field but millions of tiny toroidal magnets - closed loop that is. Look at a cavitation bubble or ring (like a smoke ring). Goes straight and doesn't react with anything that doesn't change the medium (air in smoke ring case).

so, to rotate a field of these little rings - you have to use more little rings

ball lighting is similar

Just a thought, anyone know if anyone in the Audio world would use White Noise generators to test out amp systems.

I know you can buy White Noise Generators but dont know why.

The reason i ask.
When i try to create the Explosion experiment, using a single fet system i only get the noise of the fundamental frequency from the coil when i get re-triggering, but in a 2 fet system i get white noise and explosions.
So maybe he was injecting white noise into his amp system while testing his bifilar coil speakers and found the explosions on his spectrum analyzer.

Brownian(red) noise, and sometimes, white noise, injected into an audio system is said to 'add body or dimension' to the sound. I have read Brownian noise is used to give sound 'direction' or 'shape'. haven't figured what all that means. My hearing is pretty bad

Hi guys,
When white noise is directly fed to one audio channel directly and the other channel has exactly the same signal which has been delayed there exists a spacial effect when listened to. If the delay is slowly varying say at 2Hz the effect is as if the noise is physically moving around. If the 2 signals are evenly combined it creates a deep depression and a boosted signal frequency dependant on the delay. If this combined signals delay is varied at say 2Hz then the sound emulates waves on the beach or even the sound of a jet aircraft passing by. It is used in quality hi fi as a procedure for phase imbalances and setting up parametric equalisers for those nyquists of sonic perfection. Bang and olufsen are a brand where you may find uses of white noise generators. If they still exist.
Hope this enlightens you somewhat.

@szaxx,

Very interesting, indeed!

Man Oh Man! That line is a major part of my TPU theory.

Ever hear of white/red noise used to increase the apparent size of an antenna? Say, by a thousand fold?
Or to disorient troops to the point they couldn't tell where they were or which direction was up?

Nah. Me neither

Still amazing stuff for audio. I have wondered if this was a trick on the brain or a measurable effect.

That is a transmit to receive system. Broadcast out of phase and the desired (received) signal ends up in your amplifier. ya, never heard of it...

Sr. Member Posts: 293	Hi 2 transmitted frequencies antennas spaced at 1/4 wavelength apart have the same frequency but 1transmits at1Hz off frequency the effect of this is a bi planar rotating envelope of RF in a figure 8 formation. No moving parts to this arrangement but the transmitted RF envelope effectively rotates. Cool stuff this phase fed energies

Group: Administrator Hero Member Posts: 4696	So there is a good chance SM was using white noise injected into his electrostatic speaker system or the like if he was playing with apatial effects. Hmm this is sounding like i am on the right track then with these explosions as the retriggering seems to cause it and thats when i get the random explosions appearing.

Actually there are specific harmonics that you want to suppress and in some systems signal is injected at these frequencies to null them in the output.. or not..

look at why a hammer on a piano wire is located at the 7th harmonic of that wire to suppress that frequency in the wire..

Hi all,
If you wanted to remove a ringing in an audio system you could filter it out. If you wanted to remove say a squeal when receiving morse code then you need a very steep sided notch filter.
To do the notch thing you would delay the signal and feedback this delayed signal to the input of the delay unit, the resulting notch is easily capable of dropping the unwanted noise by over 80dB there is an effect as dropping one freq also increases another all time related to the delay. If SM knew this then this would explain in clear english to me that some harmonics were bad and some were needed. feeding 2 signals into a bifilar with 1 time delayed would have a very distinct effect on the transients when sweeping around the resonance point of that coil. there would be naturally occuring peaks and troughs of several orders of magnitude and its effect is DEFINATELY worth investigating (shock waves in the ether). as to the delay I have thought of using coax as theres no iron but there is the magnetic properties of an iron coil and these would probably not be present.....
Thoughts....
Steve.
