Abstract
An energy converting mechanism includes at least two permanent magnets spaced from each other with the same magnetic poles opposed to each other, and a magnetic spring formed by the at least two permanent magnets. The magnetic spring provides negative damping characteristics or changes static magnetic energy by changing an opposing area of the at least two permanent magnets so that an output is extracted from one of the at least two permanent magnets by applying an input to the other.
