To provide a device which is relatively small, and can suppress increase in power consumption and support a larger object than conventional ones at a certain position in a space using a magnetic force without contacting to the object.

A permanent magnet is embedded in an object. Gravity applied to the object is supported by a permanent magnet located under the object or permanent magnets located over and under the object without contacting to the object. The device detects position and attitude of the object, and controls them by adjusting electric currents of electromagnets located under and over the object. The device comprises the permanent magnets, a plurality of the electromagnets, a detector detecting position and attitude of the object, and a controller adjusting the electric currents of electromagnets based on the detected result.
