1. A coupling system for a hand held device and a base, the system comprising:
the base comprising a first magnet arranged in the base to have polarity in a first direction; and
the hand held device comprising a second magnet, arranged in the hand held device to have polarity in a first direction, and an auxiliary magnet spaced at a distance from the second magnet, wherein the auxiliary magnet is arranged in the hand held device to have polarity in a second direction opposite the first direction
wherein when the hand held device is positioned next to the base with the second magnet positioned across from the first magnet in the first direction, the first magnet and the auxiliary magnet have a repulsive force between them in a third direction wherein the third direction is orthogonal to the first direction.
