Hi Norman,
Why do you think that the phenomenon can't be explained by transmission line theory? Use the theories that fit the observed experiments and not just the theories of scientific gods like Newton, Einstein and other gods of old theories. If Nature behaves in another way than a theory tells then the theory may not be correct no matter if it was made by a god of science. Just read Ivor Catt's struggle for truth. It is not popular to discredit old theories of science. Engineers look at what works or don't work. A working theory is good for designing a working circuit while a false theory gives lot of problems. Just look at the flat earthers that require very complex theories instead of the simple theories describing globular planets. Not even the religious community of the dark middle age could defend that theory.
"A true Neutral Spike, EMP is something you just have to observe to fully appreciate its power and quickness. Huge amounts of shear power carried over very small wires at extremely high frequencies."
If the pulse width gets very short the voltage gets very high because of the inductive kick back of the wire. This would transfer high power at low current. The impedance of the wire(s) (actually transmission line) can't be low like the resistance of the copper. Thus for transferring high power the voltage have to be high. When the pulse meets higher resistance the power is dissipated as heat. It is the amount of energy that destroys or evaporates metal. But of course the field strength can do so too like repelling different parts of wires (the Hutchison Effect). Even empty space has impedance and thus shouldn't be treated as empty. This is using a false theory. Thus I like the Catt way of giving even empty space physical properties. This goes back to Oliver Heaviside. The energy is in the space between the lines (electric field and magnetic field and of course the motional fields).
I don't think magnetic fields are made of lines or tubes or strings. My guess is they're just ripples or combinations of waves like in the Rhythmodynamics theory. Then matter is clusters of wave patterns becoming stable. Electric magnetic and even gravitational fields are also waves then. And then we're back to transmission line theory as the waves propagate different in different media. All the waves represents energy.
Braking a very low impedance generator like Tesla's mOhm impedance generator by shorting the output releases much of the stored mechanical rotational energy in a fraction of a second. This is very high power and this gives huge electromagnetic fields known as an electromagnetic pulse (EMP). If able to immediately mechanical brake the rotor the same amount of energy has to be transferred to the brake which may cut it apart or twist the shaft or separate the rotor from the shaft as Warren has experienced. This is huge power delivered as a short pulse. If knowing the speed and mass of the rotor the energy can be calculated and if also knowing the length of the pulse the power can be calculated too. If the motor also receives power from an external source of power like from the grid this adds even further to the energy and power.

Thank You Ole for your Text Book (totally accurate) explanation of the conventional electronics fly-back voltage amplification principles. The Neutral Spike phenomenon is non-conventional Magneto-Electric as explained by Dr. Milewski and others doing research in this EMP producing field. The study of Magnetic flux Annihilation and Reconnect is a big program by NASA and leading Universities and falls far outside of our day to day electronics studies. Research labs have been able to reproduce the phenomenon seen by the Solar Satellites recording the magnetic storms around the sun. I am certain that You guys can replicate the conditions here on this site since I personally have done it in my lab. A true Neutral Spike, EMP is something you just have to observe to fully appreciate its power and quickness. Huge amounts of shear power carried over very small wires at extremely high frequencies. I am not a Neophyte in electronics since I started by studies with DeVry Institute back in 1953. I have always kept up with the technological advances and am fascinated with the new theories and knowledge that is on the horizon. We do not know what we do not yet know!
Just saying! Norm

Very good explanation Ole. Thanks.

Hi Mick,
The resonant frequency is given by the circuit parameters. If the iron core saturates most of the inductance vanishes which increases the resonant frequency. How fast the coil is demagnetized determines the peak voltage of the flyback pulse at a given current and inductance. The product of the voltage and time is the same for the input and output pulses when the circuit parameters aren't changed. Thus an output pulse of one tenth the length of the input pulse gives ten times as high peak voltage of the flyback pulse. The secondary then transforms that voltage by the ratio of the number of turns between the primary and secondary coils. For a tesla coil this ratio has to be calculated like for a transmission line transformer. I don't think transmission line theory is strictly necessary for calculating the output voltage of an iron cored induction coil. Use the formulas for normal transformers. A capacitor is placed across the switch to limit the flyback voltage peak to a safe value for the switch. If using a power MOSFETs as switch the MOSFET probably goes into avalanche mode without this snubber capacitor. A mechanical switch will just arc across the contact points without the capacitor. What is seen as ferro resonance could be an avalanche (breakdown) through the MOSFET. This happens very fast just like ferro resonance. It may degrade the MOSFET to give it a shorter life.
How fast the coil can be demagnetized depends on its parasitic capacitance and the load of the coil. A totally open circuited coil without any capacitance will demagnetize immediately and thus induce an infinitely high voltage. Such ideal coils doesn't exist as even vacuum has a dielectric constant. Thus parasitic capacitance is formed between neighboring turns which dampens the voltage. I.e. the energy is converted from magnetic field energy to electric field energy.
The induced high voltage of the secondary coil creates an electric field between the output terminals. If close to the earth or any metal parts the field will charge those parts even through a vacuum. If the distance isn't great enough the field will punch through and discharge the field. Else the energy is stored as an electric field around the coil and in the dielectric material between the windings. When the windings share a common connection between the primary and secondary coils the electric field has to be stored on the outside of the induction coil. Metal parts close by may get charged and discharge to the air by ionization or to persons touching them. Thus be careful when experimenting with high voltages. Everything is coupled by the capacitance between them.

Ole

Warren,
The earth spike seems to work weather or not there is a ferroresonance signature on the coil waveforme, just a whole lot better when there is.
Therefore the frequency become speculative as to what resonance one is working with, be in the spark gap or the modulation or the beat frequencies.
I think a wideband approach of filling some caps from a spark gap or plasma tube as fast as they can be discharged is the ticket. This is where the experiment becomes costly as the high voltage multi mF caps are not cheap.
In the Colorado notes Tesla has an extra coil in his Magnifying transmitter that no one seems to understand what he was doing with it. I propose this is the ferroresonant modulator.
A less costly way to harves is by PF correcting the energy to work in a transformer so the field requires much research and moving slow in order not to burn up parts
