The eddy currents on the cryostat outer-vessel of an SCM (superconducting magnet) are investigated taking into account of the non-contact on-board power generator system. Numerical expressions are developed by combining a Fourier series method and an integral equation method. It becomes clear that the 5-th space harmonic field, which is due to the ground levitation coils, is a dominant factor in the eddy currents of the outer-vessel, and that a concentration of the currents occurs in the corner on the inner side of the bottom of the cryostat outer-vessel. Designs such as the distance between the two arrays of the ground levitation coils, and the lateral location of the induction coils of the power generator are also discussed.
