Ok. First question answered. Thank you. Next question: Is a metal core "ring" required to surround the conductor or can the secondary coil be a simple "air" coil positioned circumfrentially (perpendicular) to the conductor? Side newbie question; How do you include a picture or sketch in a post?

Looked there but didn't find exactly what I was looking for. Want to wrap the coil directly around the conductor without using an iron or steel ring. This config is what I'm interested in. Will it produce a voltage without an iron ring?

If I have 120 vac power cord and I wrap a coil around one of the conductors, will a current/voltage be produced in the coil? If so what are the equations that could be used to characterize this arrangement? I.e., how many coils, what size wire, etc. To produce a certain voltage in the coil?
