The electromagnet forms the inductive part of a resonating circuit. The circuit is tuned at a frequency less than that of the exciting frequency. Therefore when the distance between the object and the electromagnet increases, there is fall in inductance of the lifting magnet, the circuit approaches resonance and the coil current increases. The magnetic force on the object increases and the object moves to its desired position. Though the method is simple, for slow change in coil current the levitated object may move under influence of gravitational force and come to rest position. Hence a new circuit with Z-source inverter with shoot through is designed to bring the levitated object to its desired position.
