Abstract
Devices for detachable attachment to a ferromagnetic object and/or surface are disclosed. The device may comprise a core housing defining a pocket, a magnet disposed in the pocket, and a baseplate fixed to the magnet sheet assembly. The baseplate may include a pivot portion that engages a corresponding portion of the core housing to form a hinge joint such that the baseplate and the magnetic sheet assembly selectively pivot about a pivot axis of the hinge joint relative to the core housing. The camming mechanism may apply a camming force to a portion of the baseplate and the camming force may urge the magnet and the baseplate to pivot about the pivot axis of the hinge joint.
