Hubbard coil

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

I consider both the be pretty similar. EM phenomena is after all both electro and magnetic, not separate phenomena.

eh GK


looks like the PMH on the blue pill....

awsome job

should we expect TPU LEGOS IN WALMART SOON      

the do it yourself KIT lol

Hi,
@EMD,
Yes, I can push those vertical iron wire segments / PMH closer. Or reposition with steel keepers. Anything to keep the flux in.

@all,
The device as is stands there is held in placed by magnetization.

So,
I have distance between the center and the outers,
The segments are held in place magnetically,
And there are only 4.
Should this current setup get to where it wants to be and the parameters exceed the environment, this device will wobble out of balance and collapse.
I can add 4 more iron wire / PMH loops in the future.

No resonance, apply pulsed DC / power for a second to a pair of the center and outer coil, and then release, measure by the scope,

On previous youtubes I show the signal was jerking at half second intervals. I now know that was wrong. When the rising edge hit that is when I got the spike. But, I was only looking at the effect on the scope. The signal additively wanted to advance and grow. The continuation of the applied DC damped or squashed the oncoming pervaenace of the effect or event. Alas, my event was shorter than reality of the progression of the circuit.

So that is where the operation of this unit comes in. It should vibrate off of physical balance.

When I feel secure that this build can handle the greater event I will strengthen it with nylon cable ties. This includes low temperature meltdown as safety shutoff for later achievement.

The GK4 achieved this event but due the high speed pulses would super kick and dimish within microseconds. No sustain.

--giantkiller. One step over the line and this beacon will shine.

this beacon will shine.

Well, if it works, it is going to be a good shape for historical monument Simple

I still consider electrostriction a strong contender because there was an SM comment about piezos, the shape change is the same for either polarity of manetic or electric applied and it can occupy a section of a ring without affecting the rest of the ring. As far as being not feelable, neither is a transformer unless it is heavily loaded or cross wired. After all, piezo effect is a facet of electrostriction. Just not part of a TPU...IMO. Piezo shape change can be different for polarity applied. Not the way to produce DC. At least not that I can see.
