Purcher reports, “Apple’s patent is all about systems for harnessing power through electromagnetic induction utilizing printed coils. A system could include one or more moveable magnets adjacent to printed coils on a circuit. For example, a system could include one or more magnets that are operative to move alongside a circuit board that includes printed coils. The one or more magnets may move, for example, when a user shakes the system or when the user walks or runs while holding the device. The movement of the one or more magnets may create an electromotive force (e.g., a voltage) across the printed coils, and this force may be used to generate electric power.”
