I realize that the standard formula for the inductance of a solenoid (L = (μ₀ * N² * A) / l, where A is the cross sectional area, N is the number of turns and l is the length) is for solenoids with only one layer of wire. I thought I could find μ₀ using this simple formula, but it does not work...
I measured impedance of Z1 across the two BNC connectors, Z2 by measuring from the right BNC connector to ground, and took my oscilloscope measurements by connected Vin to the left BNC connector and Vout to the right BNC connector.
I measured the resistances across Z1 and Z2 with a multimeter and found Z1 = 473Ohm and Z2 = 164Ohm. Next I used a function generator and oscilloscope to observe the AC response.
I observed that the circuit blocks lower frequencies and allows higher frequencies through (high pass filter) which...
