Claim 13:
14. The method of claim 13, wherein the step of moving the identified ferromagnetic workpiece relative to the support with the magnetic coupling device from an initial position to a final position includes the steps of:
transitioning the magnetic coupling device from a first state of the at least three states having a first level of magnetic flux available to the ferromagnetic workpiece at the workpiece contact interfaces to a second state of the at least three states having a second level of magnetic flux available to the ferromagnetic workpiece at the workpiece contact interfaces, the second level being greater than the first level;
moving the ferromagnetic workpiece from the initial position to a second position while the magnetic coupling device is in the second state of the at least three states;
transitioning the magnetic coupling device from the second state of the at least three states to a third state of the at least three states having a third level of magnetic flux available to the ferromagnetic workpiece at the workpiece contact interfaces, the third level being greater than the second level; and
moving the ferromagnetic workpiece with the magnetic coupling device from the second position to a third position spaced apart from the second position while the magnetic coupling device is in the third state.
