Abstract: An object of the present invention is to provide a hitherto unknown, innovative magnetic propulsion device that can provide free magnetic propulsion through a geomagnetic field or another space in which a uniform magnetic field (B) is present by using an interaction with the uniform magnetic field (B). The magnetic propulsion device is configured such that wing rotors (2), which have an electromagnet (2a) wherein the upper side of the two poles therein is magnetically sealed, and which generate a magnetic field (A) toward the downward side of the two magnetic poles, are provided in an axially rotatable manner to an airframe (1) by way of an axial rotation mechanism (3). The rate and direction of the electric current that flows to the electromagnet (2a) is adjustable. The magnetic flux direction of the magnetic field (A) is reversible. The airframe (1) is held in a state of being prevented from rotating horizontally or obliquely.
