Apparatus, systems, and methods for damping movement of a first mass relative to a second mass by magnetically generating induced current are provided. A magnet is coupled to one mass and a nonferrous metallic member is coupled to another mass that moves relative to the first mass. First and second springs are coupled to opposing ends of the magnet, the magnet being positioned between the springs. A guide member channels the magnet as it moves relative to the nonferrous member, the magnet being slidable along the guide member. The magnet is in close proximity to the nonferrous metallic member as the magnet moves. Upon causing movement of the magnet by either mass, the magnet generates an electrical current in the nonferrous metallic member that induces a counter magnetic field that opposes the magnetic field generated by the current to damp movement of the magnet as it moves. |

1. A system for damping movement of a first mass relative to a second mass, the system comprising:
a first compressible element that is coupled to the first mass; a second compressible element that is coupled to the second mass; a nonferrous metallic member having a surface, wherein the metallic member is coupled to the first mass; and a magnet coupled to the first and the second compressible elements such that the magnet is longitudinally intermediate the first and the second masses and disposed in close proximity to the surface of the nonferrous metallic member, wherein a longitudinal axis extends through the first mass and the second mass, and wherein the first compressible element, the second compressible element, the surface of the metallic member, and the magnet are substantially coaxial about the longitudinal axis, and wherein when there is a translation of the first mass relative to the second mass, the magnet translates along the longitudinal axis and relative to each of the surfaces of the nonferrous metallic member, the first mass, and the second mass such that an electrical current is induced in the nonferrous magnetic member, which damps the translation of the first mass relative to the second mass. |
