Abstract
A non-magnetic case 3 made of acrylic acid or like synthetic resin has a case body 3a, a lid 3b and a right hexahedron shape. The case body 3a has a substantially spherical accommodation space 3c in which a spherical magnet body 2 having paired N and S poles arranged in a uni-axial direction is sealed together with oil or a like transparent liquid having a high specific gravity and also having a considerably high viscosity to provide buoyancy to the magnet body 2 and facilitate the rotation thereof with a lubricating action. The clearance between the magnet body 2 and the wall surface of the accommodation space 3c is set to be small such that the magnet body 2 can be rotated smoothly. The case 3 with the magnet body 2 therein is applicable to combination toys such as toy blocks and puzzle sets or various attracting articles having mutual attraction requirement. The thickness of a central portion of each side wall of the case is reduced to facilitate the attraction of the magnet bodies to each other.
