Imethods and systems for operably connecting notebook computing components using electropermanent magnets

A method of controlling a state of a dual-contact electro-permanent magnet (EPM) assembly of an information handling system comprising:

• delivering a first pulse of current in a first direction to an electrically conductive wire coiled around at least a portion of a low-coercivity magnet situated between a plurality high-coercivity magnets of the dual-contact EPM assembly housed within a chassis of the information handling system to propagate a low-coercivity magnetic field having poles that align with poles of a first of the plurality of high-coercivity magnets of the dual-contact EPM assembly;
• propagating an attractive magnetic field via a first magnetic contact situated between the low-coercivity magnet and the first of the plurality of high-coercivity magnets to attract a ferromagnetic contact housed within a peripheral device and to operably connect the peripheral device to the chassis;
• receiving a user instruction to disconnect the peripheral device from the chassis;
• delivering a second pulse of current in a second direction, opposite the first direction, to the electrically conductive wire to propagate a low-coercivity magnetic field having poles that align with poles of a second of the plurality of high-coercivity magnets;
• and
• propagating an non-attractive magnetic field via a second magnetic contact situated between the low-coercivity magnet and the second of the plurality of high-coercivity magnets that does not attract the ferromagnetic contact housed within the peripheral device.

A peripheral device attachment assembly of an information handling system comprising:

• an electro-permanent magnet (EPM) assembly including a cylindrical high-coercivity magnet disposed within a cylindrical low-coercivity magnet;
• an electrically conductive wire coiled around an outer curved surface of the low-coercivity magnet;
• the high-coercivity magnet and low-coercivity magnet disposed between a plurality of shunt plates having flat surfaces situated perpendicular to a shared cylindrical axis of the low-coercivity magnet and the high-coercivity magnet;
• an opening disposed throughout the thickness of a first of the plurality of shunt plates, and the high-coercivity magnet to allow for insertion of a ferromagnetic pin;
• wherein the EPM assembly is capable of operating in a plurality of magnetic states based on a direction of current pulse applied to the electrically conductive wire, including an attractive magnetic state applying an EPM magnetic force to attract the EPM assembly to the ferromagnetic pin.
