Abstract
Methods and systems for automatically aligning a power-transmitting inductor with a power-receiving inductor. One embodiment includes multiple permanent magnets coupled to and arranged on a surface of a movable assembly accommodating a power-transmitting inductor. The permanent magnets encourage the movable assembly to freely move and/or rotate via magnetic attraction to correspondingly arranged magnets within an accessory containing a power-receiving inductor.
