Electromagnetic propulsion device

Abstract

Abstract PURPOSE:To prevent the generation of gas and get rid of the occurrence of noise and vibration by providing plural exciting coils on the outer periphery of a fluid-passable cylinder body having an insulating property while covering the exciting coils with a magnetic shielding body. CONSTITUTION:An electromagnetic propulsion device body 1 has a cylinder body 2 on which exciting coils 3 are externally installed. By filling the inside of the cylinder body 2 with sea water and, as a three-phase alternative current is applied to the exciting coil 3 in a superconducting condition, a strong magnetic field is generated in the axial direction of the cylinder body 2 while inducing an eddy current in the perpendicular direction thereto. As a result, a repulsive force is generated in the axial direction of the cylinder body 2, obtaining a propulsion force. In this case, a magnetic shielding body 5 becomes a nonmagnetic material due to a Meissner effect forming a magnetic path in a space part. Hence, by introducing sea water from an introducing pipe 12, a ship can advance effectively. Thereby, no gas is generated because there is no electrode, neither causing noise nor vibration.
