PURPOSE:To attract cubes mutually on the whole surfaces by forming a small hollow chamber on the inside (the back) of an attracting surface for a body, freely storing a magnet into the small hollow chamber rotatably and bringing the cubes to the state in which the internal magnet is inverted and unlike poles are opposed mutually when the opposed magnetic poles of adjacent magnets have a like pole. CONSTITUTION:A small hollow chamber 2 is formed under an attracting surface 3 for a body 1, a freely rotatable magnet 5 is sealed into the chamber 2, and covered 3 with a nonmagnetic substance such as plastics, and the cover 3 is used as the attracting surface 3. The internal magnet 5 is bonded 5' with the attracting surface 3 as it is on an unlike pole by adjacent magnetic force 6, and inverted in the small hollow chamber 2 and coupled 5' with the attracting surface 3 on a like pole. When an attracting surface 4 is shaped by a thin iron piece, the internal magnet 5 is attracted to the iron plate 5 at all times and magnetic force is projected to the surface, attracted to the other party mutually as it is when adjacent magnetic force has the unlike pole, and inverted internally on the like pole and attracted and magnetized to the iron plate again and coupled 5, with the other magnetic force.
