___Good points UncleAl about all the interference. I t would be best to conduct experiment as I described it, away from power lines. At the very least their induced current in your wire may skew your results, at the very worst shock you.
___Having your wire at right angles to transmission lines will minimize the induced current, which brings to mind that every reorientation of your wire is a new experiment. You may also want to note the humidity during the experiment as static charge may also induce a voltage on the wire.
___As I understand Mr. Art Bells antenna woes, the exact cause of the voltage remains a mystery. Do you expect to explain the source/cause of a voltage if you measure one? Do you think Earth's magnetic field is a cause?
___Very interesting area of investigation.
