LC Circuit Oscillations
An LC circuit contains a capacitor (C) and an inductor (L). In this simulation, the capacitor is charged up, and then the circuit is left to oscillate, with no external power supply operating. A pure LC circuit will act as a harmonic oscillator, as the capacitor discharges, inducing a magnetic field in the coil, which then charges the capacitor up again with the opposite polarity. If there are no energy losses (which means no resistance in the circuit), then the circuit oscillates indefinitely. Energy storage in the circuit switches between energy stored in the capacitor (due to separated charges, and the electric filed created between them), and in the inductor, as the induced magnetic field.
