  "abstract": "Magnetic coupling devices may include movable pole portions. The movable pole portions may be retractable along a first direction and may be locked into place. In an exemplary embodiment of the present disclosure magnetic coupling device for magnetically coupling to a ferromagnetic workpiece is provided. The magnetic coupling device comprising: a housing; a switchable magnetic flux source supported by the housing; and a plurality of pole portions. The switchable magnetic flux source being switchable between at least an OFF state and at least one of a partial ON state and an ON state. Each including at least one workpiece interface having a workpiece engagement surface. The plurality of-pole portions including a first pole portion including a first workpiece interface having a first workpiece engagement surface and a second pole portion including a second workpiece interface having a second workpiece engagement surface.",
