Abstract
A magnetic carrier includes a housing having an interior ledge. First and second levers are pivotally mounted within the housing such that the ledge limits the angular position of the levers with respect to the housing. First and second permanent magnets are connected with the respective first and second levers for attracting a workpiece. A pneumatic piston actuator is provided on the housing for pivoting the levers with respect to the housing to selectively pivot the magnets into and out of magnetic engagement with the workpiece.
