Acoustomagnetic TPU / SEG calculation model

Yes! I think you guys are on the right track.  I suspect that an iron wire pumped by an energized magnetic field coil at one end will exhibit a potential difference across its length arising from the induced magneto-kinetic acoustic wave in the wire.  A coil at the far end can act as a pickup.   This concept borrows partly from the ancient information storage scheme known as, "delay line memory".  Here's a snippet for anyone unfamiliar with the idea;

Another kind of "delay line" memory is the so called magnetostrictive memory. This technique is based on the idea of the propagation of ultrasonic waves through a thin wire. The information to be stored is fed into a long wire by the effect of magnetostricion (the wire contracts when exposed to a strong magnetic field â€" this in turn yields an acoustic wave traveling across the wire). A bit pattern created by this effect travels along the wire to its end where the information is picked up by a piezo electric element. The output of this pickup will be amplified and fed back into the beginning of the wire loop.

I can imagine a model TPU wherein electrical pulses surf on the ultrasonic waves inside the wire, and are amplified by feedback.

Yeah, that URL sure blows a gaping hole in the "Alien Back Engineering theory".

I see this description fitting somewhat closely to the Stan Deyo coil.

Ok. We all know a not-standing-standing wave is a misnomer. The same for just 'standing wave'. If it is standing then it isn't a wave. Most use the term to describe the crossing of a source wave and its reflection.
Sorry, what is being discussed are compression waves.

I won't partake in a futher discussion of such magnetic waves not existing. You can take that up with builders of cyclotrons, fluorescent lights, and waveguides. No, plasma is not required. All the wave needs is a contained path.

Perhaps resonance is a better word here.

I like those Q values  Mark ,  magnetostriction effects (or magnetoacoustic)  are wonderful !

As we know,  bandwidth  is  equal to  F/Q,  where F is the center frequency,  so if you have a high Q value, then your bandwidth will be very very small, which means,  TUNE VERY SLOWLY AND FINE INCREMENTS or you'll miss the effect.   Also we note as F goes down the bandwidth decreases for a given Q value,   so when we start talking about   high Q and low frequencies like SM mentions,  we're talking about phenomena that can be easily missed in a lab setting.

EM

Coherent microwave radiation means that you must have  a very high Q.
You can use phonon calculator Excel file to demonstrate the electron spin precession frequency sensitivity to external magnetic field change, see how the frequency changes with given magnetic field.
The bandwidth can be only a few Hz.
