Abstract: Authors discuss the characteristics of eddy current dampers composed of a magnet and a copper plate with magnetic material. Differential integral equations governing both eddy current and magnetization were derived from the Maxwell’s equations and some phenomenological laws. The equations were simplified into a linear simultaneous equation. The results of a shaking table test validated the damping effect and the calculation method of electromagnetic force. Through numerical analysis, the size of the eddy current damper to be applied to a seismically isolated detached house was estimated, and the attractive force acting between the magnet and the steel plate was identified.
