This paper concerns the dynamic behavior of a structure coupled with an electromagnetic field. We study the coupling behavior between vibration and eddy current using the lumped parameter model of a superconducting magnet for magnetically levitated vehicles (MAGLEV). This is a simple model with multidegrees of freedom which consists of mass, spring, resistance, inductance, and differentiation of inductance. We calculate the frequency response of vibration, eddy current, and Joule loss. These results show that the dynamic behavior of a structure in a strong magnetic field is different from the dynamic behavior without the magnetic field. For example, an antiresonance point which does not appear in the structure system appears in the coupling system. We also show the modeling method to understand the vibration behavior under the magnetic field.
