ABSTRACT:
A tool (10) for handling a magnetic article (50) includes a member (12) having a jaw (18) which is movable toward and away from a member (14) having a corresponding jaw (14). A holder (34) is associated with jaw (20) of member (14) for releasably holding an article (50) in cooperation with a magnetic field. A magnet (42) is associated with and removably applied by jaw (18) of member (12) in stages. To pick up an article (50), magnet (42) is moved by member (12) to establish a magnetic field at holder (34). To release an article (50), magnet (42) is withdrawn by member (12) to withdraw the magnetic field from holder (34). The article (50) is restrained at holder (34) until gravitational force overcomes the attraction of the withdrawing field and the article separates from tool (10).
