The schematic you're showing is of an LCR resonant circuit and the recommended procedure for measurement with an inductance-capacitance meter. Please explain what bearing this has on the reduction of coil inductance from the spacing of a permanent magnet?
When the inductance meter registers a negative inductance value, it shows that the coil has reached the level
of saturation, and is building a magnetic field at frequencies above the coil's self resonating frequency. The procedure then calls for switching the meter to capacitance to continue to measure the charge in the capacitor in farads.
This procedure substantiates my claim.
