(Effects of the Invention) As described above, the electromagnetic force generator of the present invention does not use the magnetic field generated by the superconducting magnets divided into a large number as in the conventional example, but does not apply a current to the doubly arranged cylinders in the axial direction. Since a closed-loop magnetic field is generated between the cylinders by flowing the magnetic field, it is possible to naturally equalize the magnetic flux density due to its structure. Various considerations that have been made are significantly reduced, and as a result, the structure can be simplified and the cost can be reduced while improving the operation efficiency. Further, since the magnetic field is confined between the double cylinders, leakage of the magnetic field is suppressed and the magnetic field lines can be effectively used, and in this respect also, the operation efficiency can be improved.
