coils...
I see what you did now Jeanna... it's hard to say what or why the voltage is being generated. Being that low it could be picking up ambient energy or even a signal from a local source in the room.
Sitting at the table I can connect my scope to the NS coil and get a 60hz signal from it. It seems to work quite well as an antenna.
Another possibility is that the iron wire is acting like a very long transformer although without a completed magnetic circuit, if the flux in the wire has the opportunity to oscillate it will induce a voltage in the wire ( as with the core ). Maybe by connecting the core to the wire coil around creates a mild flux difference between them because of the electrical activity and causes a tiny oscillation.... might be worth investigating indeed ! Something similar to the "Cook" coil by mistake... all we need is a slight continuous imbalance to excite the electrons in a wire...

I built one today using a stick type "firestarter" and it worked. I did one modifcation later. Instead of using copper wire wrapped around, I wrapped the "stick" in a thin foam sponge and put that inside a 2" piece of copper pipe. That worked even better. I just stuck the end into a shallow dish to absorb the water. Placed into the ground it should work also if it gets enough moisture.
