Generally, a magnetic damper has a weak point that damping performance is relatively weak. The authors have been researching the high performance magnetic damper utilizing changes of the direction of magnetic poles or arrangements of magnets. In the present work, the design method of the high performance magnetic damper composed of a conductor plate and arranged rectangular magnets on its both sides is proposed. Using the modeling method the authors have been studying, when even number magnets with oppositely aligned magnetic poles are used and the area of total magnet is an almost same size of the conducting plate, the magnetic damper has highly performance. Furthermore, when the optimal number of even number magnets is chosen, it is analytically shown that the damping performance is the highest.
