    Abstract: A magnetic device for magnetically coupling to a ferromagnetic body, comprises a housing having a central bore. A plurality of pole sectors arranged within an envelope of the central bore and forming a workpiece contact interface of the magnetic device, each of the plurality of pole sectors comprising a plurality of spaced-apart pole portions arranged at respective distances, wherein a recess of a plurality of recesses separates each pole portion of the plurality of pole portions, wherein a first sector forms a first pole of the magnetic device and a second sector forms a second pole of the magnetic device. A first permanent magnet. A second permanent being moveable relative to the first permanent magnet. And, an actuator operatively coupled to the at least one second permanent magnet to move the at least one second permanent magnet relative to the at least one first permanent magnet.

    Abstract: Method and device for self-regulated flux transfer from a source of magnetic energy into one or more ferromagnetic work pieces is provided. A plurality of magnets are disposed in a medium wherein gaps of predetermined distance are maintained between neighboring magnets. And the magnets we arranged such that magnetic flux exchange may take place between the magnets across the gaps and a ferromagnetic body in close vicinity or contact with the magnets.

    Abstract: Method and device for self-regulated flux transfer from a source of magnetic energy into one or more ferromagnetic work pieces, wherein a plurality of magnets, each having at least one N-S pole pair defining a magnetization axis, are disposed in a medium having a first relative permeability, the magnets being arranged in an array in which gaps of predetermined distance are maintained between neighboring magnets in the array and in which the magnetization axes of the magnets are oriented such that immediately neighboring magnets face one another with opposite polarities, such arrangement representing a magnetic tank circuit in which internal flux paths through the medium exist between neighboring magnets and magnetic flux access portals are defined between oppositely polarized pole pieces of such neighboring magnets, and wherein at least one working circuit is created which has a reluctance that is lower than that of the magnetic tank circuit by bringing one or more of the magnetic flux access portals into close vicinity to or contact with a surface of a ferromagnetic body having a second relative permeability that is higher than the first relative permeability, whereby a limit of effective flux transfer from the magnetic tank circuit into the working circuit will be reached when the work piece approaches magnetic saturation and the reluctance of the work circuit substantially equals the reluctance of the tank circuit.
