Yeah...
Alex speaks:  The answer is simple - magnetostriction,
and yes - true - the only known gyroscopic effect ...
My knowledge speaks that magnetostriction possible only when ferromagnetic materials and magnetostriction devices included always pm magnet,
At that SM told in published this forum letter : we have spent $10k for neodymium magnets ...

Magnetostriction is not the only known source of a gyroscopic effect.

                             
Magnetostriction:
Linear effect          deforms length and twist both directions with alternating the energy applied   requires magnetic bias

Electrostriction:
Quadrature effect    deforms height and width in one direction only with alternating energy applied    requires magnetic bias

Basically, Electrostriction can be squeezed around a ring. There are many ideas that seem to fit the SM descriptions. Pursue the one that seems best to you.

Yeah, nice setup using garden hardware, chainlink fence made from at my home, Unfortunately this zinc-coated (+PVC) steel wire has very  wrong magnetic properties as core. Iron powder, even with epoxy, is much better (when reduced iron and used differnt fractions), but ...
... I dont know - is it too expensive for OU folk  - I have bought many years total huge quantity:

I use most of all Micrometals mix 26  because material properties most close to my needs  (especially AL mH/Sq.N), but sometimes high flux cores too,

for example T520  - huge core! - OD-5.2", ID-3.08", h-0.8
This material is easy to gut, to mill, turn on the lathe, drilling holes ... I have exelent CNC mill now but before I did all with Sherline mill + rotary table,
The best tools for cut it are carbide bits, mostly they have 1/8 shank:
Like Irwin 1/8" Carbide Ceramic Tile Drill Bits - Rotozip eBay Item number: 360071718108 - when bigger cuts and holes
Like 1.90mm carbide router burrs, diamond cut   Item number: 180167291446 when smaller things,
Its not like Ferrite - much more softer.
All coming grinding/dust  I do collect and use later when what ever ideas to try  - mixed with epoxy and molded ...

You right -> my poor english + I was angry ;-)  =  caused this misunderstanding - I tried to tell that when we are speaking about SM TPU - then the only known source of a gyroscopic effect,
(assumed that SM TPO does not consist flywheels or even nothing what associates with ?pieso?) But Electrostriction is not "feelable" (my own therm?) by human hands.
Because I started with my question: any known and successfully done experiment wheres no gyro wheels, where handy felt gyroskopic effect ...
Nothing more,

nice build GK,  you probably already thought of this, but squizing those loops inward will strengthen the mag field somewhat, or else it can be a great tunning mechanism.


@all,

Experimental Results:     I hooked up a coil to a variable capacitor and started tunning.     The coil has about 40 turns and it's wound on a plastic piece with a diameter of 10 cm perhaps.  The coil is wound in a single layer and it's height is about 1.5 cm or so.   Anyway,  around this I have a toroidal winding made with lamp cord, so it has two conductors, however, I connect the conductors in series.   Now here's the interesting part.    I was watching on the scope to see if I tune in any unsual stations or resonance, and it appears I am, as I turn the variable capacitor there is a frequency always present that changes.  This seemed puzling to me, what sets up the oscillations I thought?   Then zooming out, I noticed they start suddenly and decay away  (max voltage at start point about 0.25 volts). Almost as if an impulse triggers the oscillations, which ofcourse varry in frequency depending on the variable capacitance.  Then zooming out some more I notice the pattern repeats, every 8.3 ms, which implies every 120 Hz.   So an impulse every 120 Hz triggers and pumps my resonant tank. Isn't that interesting.      Something is causing these impulses and triggering the oscillations of my tank circuit, (loop antenna and capacitor) and it appears to be the second harmonic of the 60 Hz power grid, but what is it?    Can somebody else do this simple experiment and see if they see the same thing?   I'm not sure where it's comming from, the power lines in my community are underground and I even performed this experiment with all the lights off in the house.  Right now I'm thinking if I can get that much voltage, well with a bit of engineering I should be able to pull energy right out of the thin "air"    LOL

Howdy Y'all,

EMDevices, 60 Hz is everywhere, even with the lights off.  It is more than the AC wires it is the earth resonating with the AC distribution grid.  When I was experimenting with the Soft Particle Reactor I noticed this.  I have a neon lamp and a florescent lamp above my bench.  The neon lamp made sharp noise that had a decaying ring wave form.  I turn that off the interference goes away.  Then I had a small amplitude sine wave interference.  When I turned off the florescent lamp that went away, almost.  There was still a tiny 60 Hz sinewave in my wave form which was probably the power strip and a few other things still attached to AC on my bench.  You take take parasitic power off the grid with a 60 Hz tank.  Big iron inductor and a cap to make the circuit resonate at 60 Hz...

Blessed Be Brothers...
