Problems with Naudin?s current transformer method

Naudin used a toroidal wound mains transformer as a current transformer. This is only possible once without resetting. If a unidirectional pulse current is passed through the centre the toroid becomes magnetized and the field remains in the core unless a demagnetizing field is applied to reset it or an air-gap is introduced. This is due to the finite area of the BH loop.
To prove this assertion a toroidal transformer core wound with 400 turns loaded with a 100 ohm resistor has through its centre a non magnetic 316L 3 mm thick stainless steel rod. This is connected through a high current FET switch to 0.2 F capacitors charged to 37 volts.

Firstly, the stainless steel rod is impulsed once, this leaves the core magnetised. The stainless steel rod then is impulsed again but this time the impulse produced across the 100 ohm resistor of the current transformer is stored.
Now the current transformer is rotated 180 degrees so that the face which was left now faces right. The current direction in the stainless steel rod remains unchanged.
Again the stainless steel rod is impulsed and the results stored.
As can be seen the toroid has now dumped the stored energy giving a much larger pulse area.

So how would this effect us applying multiple pulses to the carbon rod? 
Would the pulses have to be AC instead of DC for it to work?

I wonder how this effects the use of toroids in the  "Thane Heins Perepiteia"

Maybe you should post this info there as well.

Abbarue,

The problem is that after the first pulse the core is nearly fully magnetised so applying another pulse in the same direction cannot produce a further increase in the core magnetisation, this implies very little change in magnetic flux is possible so the measured output pulse is vastly smaller than it should be. If the core were demagnetised a full change in magnetic flux can occur proportional to the size of the input pulse.

After every pulse the core needs resetting to its zero flux state. This is best done by incorporating an small "air gap" (a piece of paper will usually do). Alternatively a single insulated copper rod is mounted through the toroid, parallel to but not touching the carbon/tungsten and another pulse equal and opposite to the first is  applied. I am experimenting with two half C cores from an old power transformer  as the current transformer and a few pieces of paper as the "air gap" to demagnetise it. There are several other ways more or less hassle ridden, such as demagnetising with heavy current AC, the best way is to get a broadand current probe but these are very very expensive.

Regarding the "Thane Heins Perepiteia" thread I have not been following it so I do not feel it worth anything offering my opinion.

Problem with Naudin's current transformer method: continued

Cutting a slot through the toroid with a hacksaw so it is no longer a closed circle cures the flux remanence problem of post 835 etc. Now reversing the toroid 180 degrees has little or no effect on the pulse size or shape. However care should be taken to ensure the flux density in the core is not too close to saturation, the slot helps in this respect.

@mikewatson
I don't know why no one else has mentioned this point, at least I don't remember reading it.
But making an air gap in a toroid sounds very useful in another way.
A toroid could be cut completely in half to get 2 air gaps.
Then each half could be wound to whatever number of turns one wants.
This would make it much easier to wind a toroid then trying to pass the wire through
the center each time.
Does it mater if there are 2 air gaps 180 deg. apart?
