Illustrative examples include a system for coupling a first electronic device to a second electronic device. The first electronic device may include a housing having a first engagement surface and a first magnet array. The first engagement surface may be adapted to receive the second electronic device. The second electronic device may include a second magnet array. An actuator coupled to the first magnet array may move the first magnet array relative to the housing and the second magnetic array, to attractively couple or repulsively de-couple the second electronic device from the first electronic device.
