# Variable field magnetic couplers and methods for engaging a ferromagnetic workpiece

## Abstract

Magnetic coupling devices are disclosed which may be configured in at least three states. The various states may be provided through one or more of altering a position of a permanent magnet relative to another permanent magnet and altering a current level in a coil surrounding a permanent magnet.
