This paper describes the novel sextupole rails electromagnetic launcher. The interaction between the toroidal magnetic field and the orthogonal toroidal currents results in the generation of axial acceleration force. The sextupole rails electromagnetic launcher can solve the problems of magnetic shielding with no need of shielding coils or materials. This paper describes the theoretical assessment of the propulsion force and magnetic shielding based on analytical calculations, and the corresponding numerical validation by finite elements. The numerical simulation results indicate that the sextupole rails electromagnetic launcher has great axial acceleration force and productive magnetic shielding effect.
