We onsider a two dimensional model based on the transverse magneti formulation of the eddy urrents problem for the ele tromagneti part and on the motion equation of a rotating rigid body for the me hani al part. The magneti system is dis retized in spa e by means of Lagrangian nite elements and the sliding mesh mortar method is used for a ounting the rotation. In time, a one step Euler method is used, impli it for the magneti and velo ity equations and expli it for the rotation angle equation.
