Abstract

PURPOSE:To exactly remove a material attracted to attracting member by providing means for cancelling the coercive force of the attracting member at a position isolated from the attracting member. CONSTITUTION:Guides 2, 2' and 3, 3' are connected with connecting member 1. A permanent magnet 6 is disposed at soft magnetic attracting members 4 and 5 respectively, and the material to be attracted is attracted to the attracting members 4, 5. A part of the attracting member 4 is extended, for example, to the side of the member 5 at the position isolated from the members 4, 5, an extended part 4' is thus formed. Further, a part of the member 5 is also extended, and an extended part 5' is thus formed. When an actuating member 7 is pulled up so that the permanent magnet 6 is moved to the extended parts 4', 5', magnetic flux for cancelling the coercive force of the members 4, 5 when the members 4, 5 attract flows through the members 4, 5. Thus, the material to be attracted can be exactly removed.
