This means that unlike other methods of damping, such as constrained layer damping, the dynamic response and material properties are unaffected by its addition into the system. Furthermore, many applications require a damping system that will not degrade in performance over time. This is not the case for other viscous dampers; for instance, many dampers require a viscous liquid which may leak over time. These two points are just a few of the many advantages offered by eddy current damping systems. The most widely researched and well-developed area of eddy current damping systems falls in the category of magnetic braking. While the research in this area will be thoroughly discussed, the literature is very dense and every paper cannot be reviewed. The work in magnetic braking will be presented first, followed by studies into eddy current damping of rotating machinery, and finally a wide range of research using eddy currents for dynamic systems will be presented. The concept of using eddy currents for damping purposes has been known for a considerable time, with manuscripts dating to the late 1800s. Therefore, the history of the eddy current damper will not be presented and only work from the past few decades will be revilements are generated in the conductor. Cadwell,
