Abstract
This disclosure is directed at least partly to reducing an acceleration of a magnet when a magnet is moved toward an attracting object. An apparatus may include a dampening mechanism to dissipate kinetic energy of the magnet as it traverses within a housing from a first position to a second position. The housing may be at least partially coupled to another surface as a result of a magnetic attraction when the magnet is located in the second position. The dampening mechanism may include use of a fluid and/or gas that is displaced by the magnet to slow acceleration of the magnet as the magnet traverses between the first position and the second position. In some embodiments, the dampening mechanism may be implemented using threads that cause rotation of the magnet or by rollers that slow acceleration of the magnet.
