The twin-lead should be open-ended. Can't tell if it is in your pic.
Your wrap is where I was much earlier. The capacitance between twin-lead turns is cancelling anything produced by the wrap. I suggest trying for a conductor spacing between turns of 2 to 2.5X the distance between the conductors in the twin-lead.
The loop is completely isolated from the twin-lead? (except for capacitive coupling).
BTW: I use isolated active scope probes on this type of experiment. You can get much the same capability by summing two scope channels.
No part of the DUT can be connected to ground or capacitive coupled to a metal bench top.
I suggest you not throw any money or much time into this until I can find some configuration that assures some definite level of positive result.
Yes, my twin wire was open ended, but I did use a grounded scope lead. I will try again with a differential amplifier, and use a battery to drive the heavy wire loop. Do you have any numbers you can throw out or a picture of your device for a better starting point? GK: I have also been thinking along the lines of a regenerative circuit. Are you running it in the audio or RF range. Can you show any results? BTW, the second link doesn't work for me, "page not found" error.
