diameter of wire = distance between 1st and last turn ÷no of turns or
I will coil the wire like a flat spring, round and round until it becomes a wide disc. I will nite the number of turns I have made this way. Each turn contributes twice the width (or diameter) of the wire to the disc. I will measure the disc with the meter wire, and I will divide by twice the number of turns to obtain the diameter of the wire.
