This paper discusses an indirect suspension of magnetic target through an actively controlled permanent magnet. This proposed system consists of an electromagnet, a permanent magnet and a target mainly. The dynamics of levitated bodies are restricted in one dimension, and the target issufficiently away from the electromagnet. The target is suspended by a proportional - derivative control with respect to the position and the velocity of the permanent magnet. The aim is to model the dynamics of levitated bodies by magnetic charges. The behav-iors of levitated bodies near the reference positions are studied numerically and experimentally. As a result, it is shown that the behaviors of levitated bodies near the reference positions can be described by the proposed model.
