Otherwise you just made yourself a frigging choke for your kick.

I do not fully agree here. The low-passing effect is back EMF effect (RC effect, with induced energy being analogous to capacitance). The pulse will fire through the whole toroid first, then you'll notice the low-pass effect. Statistically it is a low-pass effect, but physically the required movement will be there.

The problem here is that if your reasoning is correct, there is no need to use any core whatsoever. Even a PVC tube core works as a low-pass filter being a capacitor which adds its surface charge to the output with a bit of time delay. And then again, ANY coil is a low-pass filter. How you'll treat this fact?

I believe the Helmholtz coils were to be of iron instead of copper.

This solely depends on the core. Here http://en.wikipedia.org/wiki/Helmholtz_coil this coil is seemingly copper, but with plexiglass core. Plexiglass has some required capacitance - it may be even much more efficient at sustaining the inductive charge than any metal.

Beside that PESWiki mentions a man who runs small motors by using plexiglass and a small coil. The same effect we are all looking for I think, take a look.

i got a link for you all

i did this so long ago i almost forgot about it it is in half baked lol

plexi ring welding wire copper and a crystal lol

hummm

i may even  still have the coil laying round some where .....

      You are getting way ahead of me.  I am just trying to get the kicks to negotiate the torroid. Then have the iron restore the kick windings magnetic resonance with the Earth field.  This restoration is what back emf is all about.  What makes a magnetic field collapse?

Well, back EMF has nothing to do with Earth's magnetic field. Back EMF is energy returning back to circuit after it bounced around in the core. In the sense it is like a capacitor discharge. Hence, when it is added, an RC (low-pass) effect is created. Back EMF opposes forward electric current hence creating a resistance at certain frequencies. Gibbs' oscillations are not back EMF itself, but a result of back EMF acting upon an impulse signal. In this sense pulse may "fire" through the whole toroid just to be subjected to back EMF.

One idea about 5kHz pulse frequency related to things said by me. As far as I know, cores all have a pretty wide frequency response range. If the theory of how this TPU works is valid, one should choose a core (or coil arrangement) whose low-pass corner frequency is as low as possible. At the same time it is hard to find a core with a very low low-pass corner frequency. For example, if this frequency is 3kHz, 5 kHz pulsing may seem pretty logical. If you can find even a "larger" core you may further lower the pulsing frequency (but its voltage should be increased proportionally); anyway small-format TPUs are limited with core choices. If frequency of core is high you'll need to increase pulse frequency.

To check core's frequency response you'll need to sweep the coils with a sinewave of frequency raising logarithmically. This way you'll be able to measure frequency response of the coil.
