发明名称 Magnetic display device consists of large hollow wooden block containing magnet near outer surface and small wooden block above, containing magnet with inverse polarities, connected by wires to large block
摘要 The display is composed of a large hollow wooden block (1) containing a magnet (3) near to its outer surface (20). Above this floats a small wooden block (2) containing a magnet (4) with inverse polarities to that of the large block. Flexible wires (6,7) connect the two blocks to stabilize the small block and prevent it from overturning by the repulsion and attraction of the magnets. Light objects (5) are placed on the small block outer surface.
