Abstract

PURPOSE:To maintain the inner container floating without contacting the outer container by preparing a magnet so that the magnetic flux acts on an appropriate spot of at least either of the inner-and-outer containers. CONSTITUTION:Within the magnetic fluid 2, with which the outer sphere is filled, an inner sphere 3 with a built-in fast spinning toy is accomodated and within an outer shell of the outer sphere 1, for instance, in the eight vertexes of a regular hexahedron contacting the inner surface of the outer sphere 1 the permanent magnets 4 with the equal magnetic flux density are arranged. By said constitution only near the magnet 4 the apparent specific gravity of the fluid 2 becomes big and when the inner sphere 3 nears the wall of the outer sphere 1 it receives the repulsin from said part to be pushed back into the central direction thus the inner sphere 3 is always maintained near the center of the outer sphere 1.
