@Mannix,

Here ya go...

Below I use the term loosely, wherever you have two sets of coiled wire next to each other that are magnetically coupled (as in the TPU) you have this transformer effect.

The above is what happens when a 'tranformer' goes into saturation.
The blue is the voltage and the red is the current on the primary.

As the voltage rises the transformer goes into saturation. At saturation the primary appears as a short so the current surges because the effective resistance has gone to zero.

What is nice about this peak is that it is a high current peak but without any of the pesky back EMF when you switch a circuit.

Zip several of these waveforms around your coils a few times and combine them together in other 'transformers'...

Tesla created radiant energy using high voltage and high current spikes.

So what you may ask ?

When using a mosfet to pulse you get ringing on both the on and off of the pulse. Ringing is by definition AC. Tesla has made it abundantly clear that radiant effects require DC pulses, with no return of currents. This is why  this transformer effect is very interesting. The current pulse appears without any ringing. Althoug the above effect is for an AC signal causing the saturation. You could force the saturation by apply a DC voltage to the transformer. Thus ensuring that saturation only occurs in one half of the cycle thus only getting current pulses in one direction.

Give yourself 10 out of 10!

Much of what I see on here concentrates on voltage pulses, some using resonance, but without any real current behind the voltage pulses. The exeption being those that have some sort of capacitance behind the pulse. e.g. the stun gun examples.

We could go down the road of high voltage capacitors, spark-gaps,  etc. but SMs devices don't appear to exhibit sparking artifacts. e.g. white noise on TV screens. There is a video where the TV is working within several feet of the TPU. I've had spark gaps going that cause noise from 10's of meters.

Therefore another method is required to generate high voltage, high current pulses without switch ringing. As the above meets this requirement, this is why this setup is interesting.

Here is my study of firing the control coils in sequence with a ring counter circuit to make a rotating field.

Nice coils. What components are you using for the ring counter ? I assume it's a 555 timer or func generator -> shift register -> mosfet driver -> mosfet->coil   type of arrangement ?

I had been using one of these:
http://www.oceancontrols.com.au/motor_controller/microstepping_motor_controllers.htm

I had four 'motor' coils arranged on a wooden board in typical 2 phase motor arrangement but all Norths pointing towards the center, so basically pulsing north facing towards center, magnetic pulses in a circle. I placed another air core solenoid over the whole arrangement. i.e. Like placing a pipe vertically over the coils so the circumference of the one pipe covered all the 4 coils. In otherwords this solenoid is at 90 degrees to the four coils.

I placed 12 volts DC from a car battery across this solenoid in series with a 15ohm 20watt resistor.

A function generator pulsed the microstep controller. I had the whole thing running at around 6.8Khz. I was looking at waveforms on the scope to see if the DC coil, even though it was at 90 degrees to the other coils, affected the scope waveform. No real difference detected.

The DC coil was connected to one battery and the microstep and the four coils to another battery. I used two batteries is so that there would be no possibility of electrical noise from the 4 coil switching going over the wires to the DC coil via the common connections to a single battery.

The connection to the DC coil came loose at the battery and was sparking and then POOF the whole microstep controller goes up in smoke. You could smell burnt up electrolytic capacitors and could see resistors burnt out on opening the box up.

Theoretically there should have been no coupling between the DC coil and the four coils... so this is a very interesting result. However, I can't afford to burn up $99+, each time I try this!, so now looking for a cheaper homemade circuit, to continue the 'burning' experiment.

@ bob.rennips

sorry about the controler man.

do you have a pic of your setup

thanks
