Hello forum members,

Are there any online calculators or is there a mathematical formula that can be used to calculate the target impedance of the voice coil based on the gauge of the wiring, the number of winds etc?

For example, if my initial target is an 8 ohm voice coil and I am using 38AWG wiring, what would the optimal method be for determining the number of winds to get to an 8 ohm voice coil? I have a standard LCR meter and a high precision LCR meter as well, I had thought about periodically melting the wire during the winding process to measure the inductance/capacitance/resistance of the coil on the jig to derive a formula for the length of wiring/number of winds needed, but that's probably not the right approach nor do I think it would work based on the wire still being attached to the spool feeding the winding jig.

I am also curious about how the number of winds affects the magnetic field collapse. I am sure these are basic electronics 101 questions but I can't find any direct answers from the research I've done so far.

Thanks in advance for any input!
