These magnetic kinetic amusement devices have plural magnetically coupled elements that exhibit intermittent, alternating motion as energy is interchanged between the elements. In one embodiment, plural vertically spaced arms are mounted for pivotal motion about a common vertical axis. Each arm has a pair of magnets at its extremities. As it rotates through a partial revolution, its kinetic energy is magnetically coupled to an adjacent arm. As a result, adjacent arms alternately rotate through fractional revolutions, providing quantized motion that is fascinating to watch.
