As a promising method to provide on-board service power at running of superconducting Maglev vehicles, a linear generation system is being investigated, in which reaction high harmonic magnetic fields generated by the levitation normal coils on the guideway produces an electromotive force in the generator coils on the outer vessel surface of the on-board superconducting magnet. To obtain larger power in this linear generation system, we developed a superconducting magnet with a short distance between the sectional center of a superconducting coil and the surface of an outer vessel, with the outer vessel having hollow parts. This paper describes the construction of the superconducting magnet we developed and manufactured on trial and electro-magnetic disturbance test results of the superconducting magnet.
