Abstract: A method for producing a switchable core element-based permanent magnet apparatus, used for holding and lifting a target, comprised of two or more carrier platters containing core elements. The core elements are magnetically matched soft steel pole conduits attached to the north and south magnetic poles of one or more permanent magnets, inset into carrier platters. The pole conduits contain and redirect the permanent magnets' magnetic field to the upper and lower faces of the carrier platters.

Aligning upper core elements “in-phase,” with the lower core elements, activates the apparatus by redirecting the magnetic fields of both pole conduits into the target. Anti-aligning upper core elements “out-of-phase,” with the lower core elements, deactivates the apparatus resulting in pole conduits containing opposing fields.
