Exchanging signals wirelessly between devices

A system comprising:

• a first wireless communication unit of a first device;
• a second wireless communication unit of a second device;
• a first magnetic member disposed within the first device to magnetically couple with a second magnetic member disposed within the second device when the first and second devices are to be placed within proximity of each other, wherein the first and second wireless communication units are to exchange signals between the first device and the second device over a wireless communication link formed by the magnetically coupled magnetic members;
• and
• electrically conductive material to coat an outside surface of the first and second magnetic members, wherein when the first magnetic member is to magnetically couple with the second magnetic member, the electrically conductive coating of the first magnetic member is to make contact with the electrically conductive coating of the second magnetic member to power the second device.
