Research Abstract	This application is described light-driven method for diamagnetic material in numerical analysis and experiments. The proposed system consists of permanent magnets, temperature-sensitive ferrite and light source. Since diamagnetic material can levitate passively, it was driven efficiently without contact. Magnetic susceptibility of temperature-sensitive ferrite depends on its temperature controlled by photo-thermal effect. Magnetic flux distribution changes by heating temperature-sensitive ferrite. Therefore diamagnetic material can be control without contact. Noncontact light-driving possibility of diamagnetic material is derived from numerical analysis in one and three dimension. As a result, diamagnetic material is successfully controlled by using soldering iron instead of light.
