First shot is of dual coil toroid at eighth H returning -39uA and next is single coil toroid at eighth H returning -27uA

Hi Luc,

It is very interesting the negativ current draw increases as you go higher in frequency. 

This is a very unusual measurement result so that if you do not mind I would like to suggest some simple measuring methods to make sure whether we can really trust in the negative polarity sign you experience. Please postpone what I asked yesterday for testing (Q measurement of the toroidal cores).

Would you use your last setup again where you were at 17.36-18.12kHz frequency already and the currents were  -39 and -27uA.

Alternative measurement suggestions for testing the polarity change:

#1  If you happen to have a 100uA or 1mA analog meter or an analog multimeter that has DC mA measuring range that would be the best. You would connect such an analog meter in series with the battery positive pole.
(On certain analog multimeters the most sensitive volt or amper range is the analog meter itself with its 50-100uA basic sensitivity.)

#2  If you do not have an analog meter at hand, you may use a digital multimeter that has a 2mA DC measuring range (most sensitive in general, some may have 200uA DC range as well) and also connect such DMM in series with the positive battery pole. (positive input of the current meter goes to the positive pole of the battery)

#3  If you have a DMM that has 200uV DC input voltage measurement range (very rare and such DMMs are expensive), then please place its input in parallel with the 10 Ohm (you may remove the wires going towards the Fluke, no need for them for that moment).  (positive input of the DMM goes to the positive pole of the battery, the negative input goes to the 10 Ohm resistor leg that continues towards the toroidal coil)

It is NOT interesting what the current amplitudes really measured with these alternative methods, it is the polarity check that would count.

I believe that unusual results should be checked manyfold to exclude any possibility for errors.  I want to help in this effort.

We've only been using one end of the magnet.  The other end isn't being used
as shown by "Configuration A", in the below image.  "Configuration B" is using
both ends of the magnet by using two toroids.  "Configuration C1" is showing
2 gapped toroids for illustrative purposes only.  "Configuration C2" is showing the
same 2 gapped toroids in "C1" overlapping each other to make a Figure 8, with a
magnet connecting the two.  "Configuration B and C" could be using a dual coil for
both toroids, or a combination of dual and single coils.

Insanity is doing the same thing over and over again, and expecting a different result.

God will confuse the wise with the simplest things of this world.  He will catch the wise in their own craftiness.

Hi Gyula,

I don't have an analogue meter. So I did the test you asked using a good quality DMM that has a DC 000.0uA resolution to measure the the amp and I used my Schlumberger 7150 plus to measure the voltage across the 10 Ohm resistor. It has a DC volt resolution of .000000dcv

The results are Minus -003.3uA on the current meter and Minus -.000337dcv on the voltage meter.

I don't quite understand why you want me to do this test since this is the exact setup of my capacitor bank meter (measuring the voltage across a 10 Ohm resistor using my hi resolution meter)... but maybe you didn't understand that. Anyways, I did the setup as you asked to satisfy your request or remove any possible connection error.

Luc

ADDED

Something is not right with this test If I use the current meter at the same time as the voltage across the 10 Ohm resistor as this is not giving a true current reading. Did you want each test to be separate?

ADDED

Okay, maybe this is what you want. The current meter is in series between the battery + and the resistor.  So current meter red lead is connected to + of battery and the black lead is connected to the resistor. The voltage meter red lead is connected with the black lead of the current meter side of the resistor and the black lead is connected to the coil side of the resistor.

Results: -244.5uA on current meter and -.000244vdc on voltage meter

I think this is what you want ;)

Hi Luc,

Thanks for all the tests, I am even more puzzled now... and this is not a complaint of course  :)   :-\ 

Basically I meant to get rid of the hi res Fluke microvolt meter because I suspected its ground sees the computer grnd and the signal gen grnd and at the same time it has to measure a few microvolts amplitude floating on 12V DC  while the pulses has an increasing frequency: this may challange its common mode behavior and the sampling process inside it may suffer.

Well this is not case, so for the time being I have no explanation (of my own) for the negative polarity...

Thanks,  Gyula
