Phil,
You need to trust me on this one. 200 volts is considered HIGH voltage. A wall outlet produces a little over 200 volts, peak. If you have been shocked before, consider yourself lucky, very lucky!
You need to measure the inductance in an air core first and then slip the core into the coil to measure the difference. You get an idea of what the permeability of the core is by solving the inductance equation for permeabilty when you know the inductance in both cases. I suggest a trip to the library for a copy of the ARRL Amateur Radio Handbook. You will find some discussion on inductance and measuring techniques.
