Abstract: An electrical plug and receptacle relying on magnetic force from an electromagnet to maintain contact are disclosed. The plug and receptacle can be used as part of a power adapter for connecting an electronic device, such as a laptop computer, to a power supply. The plug includes electrical contacts, which are preferably biased toward corresponding contacts on the receptacle. The plug and receptacle each have a magnetic element. The magnetic element on one of the plug or receptacle can be a magnet or ferromagnetic material. The magnetic element on the other of the plug or receptacle is an electromagnet. When the plug and receptacle are brought into proximity, the magnetic attraction between the electromagnet magnet and its complement, whether another magnet or a ferromagnetic material, maintains the contacts in an electrically conductive relationship.

Abstract: Magnetic systems can include a controllable magnet array and a fixed magnetic array. The fixed magnetic array can include an array of permanent magnets having alternating polarization direction transverse to the array. Some controllable magnet arrays can include electropermanent magnets (EPMs) arranged end-to-end, with pole pieces between them aligned to the permanent magnets of the fixed magnet array. Each EPM can include a permanent magnet having a fixed magnetic orientation lateral to the array and antiparallel to the permanent magnet in an adjacent EPM and a switchable magnet whose magnetic orientation can be switched between parallel and antiparallel to the permanent magnet in the EPM.

Abstract: A method of magnetizing a multi-pole magnet includes the steps of obtaining a magnetization coil having a magnetization zone and a central axis, and positioning a magnet within the magnetization zone. The method also includes positioning at least one pair of shield bodies including a conductive material proximate the first and second surfaces of the magnet, with the shield bodies being aligned together to cover both sides of at least a first region of magnet and expose both sides of at least a second region of the magnet. The method further includes energizing the magnetization coil to generate an applied magnetic field within the magnetization zone that is sufficient to induce eddy currents in the at least one pair of shield bodies and to magnetize the exposed second region of the magnet.
