ABSTRACT:
A superconductor composite body have a plurality of superconductor elements. Each of superconductor elements has such a volume that the superconductor element is not magnetically saturated with a magnetic flux applied to the composite body. The superconductor elements are assembled in one plane into one body in a such manner that superconductor elements are electrically coupled with each other when the superconductor elements are united with the electrically conductive non-magnetic material. The superconductor elements can be simply secured or fixed to a substrate with an adhesive or other suitable manners. When the superconductor elements have a thickness 1 mm or more, a sufficient levitation force can be generated provided that a condition of the lateral area of the assembled elements which are determined by a magnetic field and a critical current density is satisfied.
