A long, tightly wound solenoid is placed on a cylindrical iron core with magnetic permeability m and conductivity l. The solenoid is closed to a capacitor, resulting in a circuit with a resonant frequency w (figure). The core radius is r0, leakage in the capacitor is insignificant, the winding and connecting wires can be considered ideally conductive. Determine the quality factor of the circuit.
