PROBLEM TO BE SOLVED: To easily separate a wiring pattern on a magnetically attractive thin board from its frame by arranging regular parallelepiped magnets in the traverse and vertical directions with Fe plates inserted between the adjacent magnets, resulting in alternate arrangement of the magnets and plates in the vertical direction and magnetizing the magnets in the vertical direction so that the identical poles of the adjacent magnets 2 face each other with the Fe plate 3 between. SOLUTION: The magnetic attractor 1 for separating part of a wiring pattern on a magnetically attractive thin board from its frame comprises rectangular has parallelepiped magnets 2 which are arranged in the traverse and perpendicular directions W and D with their lengths parallel to the direction W and held in a housing 4. Fe plates 3 having the same length as that of the magnet are inserted between adjacent magnets arranged in the direction W, i.e., the plates 3 and magnets 2 are alternately arranged in the direction D and the magnets 2 are magnetized in the direction D so that the adjacent magnets face their identical poles each other with the plate 3 between. |
