N2 - Structures that are exposed to amagnetic field experience magnetic forces. As these forces are geometry dependent they vary with the displacement of the structure that can result in an additional stiffness. Furthermore eddy currents induced by the movement of the structure can lead to an increased dissipation resulting in a higher damping value for the mechanical part of the system. This paper introduces calculation techniques for predicting these effects and validates them with measurements done on a simple set up in the lab.
