LEVITATOR ABSTRACT OF THE DISCLOSURE: A levitator which is mounted on a space station, for example, for use in material science experiments in space. The levitator has a position detector for detecting the position of a sample, a variable power supply whose output voltage varies in accordance with the signal output from the position detector, a pair of planar electrodes connected to two ends, respectively, of the variable power supply and disposed in opposing relation to each other, and a ring electrode disposed so as to surround each of the planar electrodes and to which is applied a higher voltage than that applied to the corresponding planar electrode from a DC power supply, thereby holding the sample stationary at a desired position by means of the planar and ring electrodes. The levitator further has a means for rotating the sample being held stationary. Thus, it is possible to rotate the sample in a controlled manner and hence possible to carry out an experiment in which the sample is uniformly heated in a microgravity environment.
