Embodiments are disclosed for a stylus comprising an energy storage device for powering active functionality of the stylus, and a charging circuit electrically coupled to the energy storage device and configured to provide charging current for recharging the energy storage device. The stylus further comprises a magnetically-attractable element comprising ferromagnetic material disposed in a ring formation on an outer surface of the stylus, the magnetically-attractable element being electrically coupled to the charging circuit to form a terminal of the charging circuit, and the magnetically-attractable element being configured to be received on a dock via magnetic attraction to a permanent magnet of the dock to bring the stylus into a docked position in which the magnetically-attractable element contacts a charging contact of the dock to thereby cause the charging circuit to receive charging current from the dock. |
