Similarly, the wireless circuitry portion 614 of the connection interface 600 is indicated within the second dashed bounding box. The wireless communication circuitry 606 is connected to a circuitry lead 636, which is mechanically and electrically connected to a magnetic circuitry connector 622. The magnetic circuitry connector 622 may be formed by a magnetic core of a second magnet 644 covered by a conductive coating 646. The second magnet 644 may be a neodymnium magnet material or other appropriate magnetic material with sufficient strength to maintain a desired mechanical connection. The second magnet 644 may be coated or plated (e.g., by electroplating or chemical deposition plating) with an electrically conductive material, e.g., nickel, silver, gold, copper, zinc, or platinum, to form the conductive coating 646. The circuitry lead 636 may be soldered to the conductive coating 646 of the magnetic circuitry connector 622 to provide both a mechanical and electrical connection between the two. In the context of
