PROBLEM TO BE SOLVED: To provide a magnetic attraction device in which an adsorbed object, which is adsorbed and supported on a supporting surface, can be easily removed by a labor as little as possible from the supporting surface.SOLUTION: A magnetic attraction device comprises a permanent magnet 36, a first core 48 surrounded by the magnet, a coil 40, and a second core 42 surrounded by the coil. The magnetic attraction device is configured in such a manner that a magnetic unit 30 for generating magnetic flux discharges magnetic flux from a supporting surface 58 on which an adsorbed object 106 is adsorbed and supported is provided, an edge cutting means 66 equipped with a projection 72 projected from the supporting surface 58 is also provided, and a part of an adsorption face 108 facing the supporting surface 58 for supporting the adsorbed object 106 is pushed up from the supporting surface 58 by the projection 72 of the edge cutting means 66 thereby separating the part of the adsorption face from the supporting surface. |
