Abstract
Some embodiments can include a retention mechanism having a first component including a first clasping surface and a first magnet having a first polarity as well as a second component having a second clasping surface configured to be alignable to and to coordinate with the first clasping surface. The second component can have a magnetic assembly having an effective polarity that varies in accordance with a electric current pulse received at the magnetic assembly, where a magnetic circuit is formed between the first magnet and the magnetic assembly, and where when the effective polarity of the magnetic assembly is the first polarity, the magnetic circuit is repulsive causing the first and second clasping surfaces to separate otherwise, the magnetic circuit is attractive causing the clasping surfaces to come together.
