To solve a problem wherein equipment for generating magnetic field in a track is required in a linear motor car propelled by electric force by an action of an electromagnetic field, a course is limited, equipment cost is high, and a material around a propulsion device is required to be heavy in electromagnetic induction propulsion to be used in a vessel, etc. and the electromagnetic induction propulsion can be virtually used at only the sea.

This electromagnetic propulsion device is in contact with an environment in which current flows such as a material of gas or liquid in which current is easy to flow and vacuum. In the electromagnetic propulsion device, magnetic poles 21 and 22 to generate the magnetic field in the environment and electrodes 31, 32, 33 and 34 to make current crossing the magnetic field flow are installed. Voltage is applied between the electrodes 31, 32, 33 and 34, current is made to flow and magnetic field is generated from the magnetic poles 21 and 22. The current flowing between the electrodes 31, 32, 33 and 34 has property to hold the state, force is generated in the electromagnetic propulsion device by an interaction with the magnetic field generated by the magnetic poles 21 and 22 and disappears in a short time since the current changes the track. By generating current and magnetic field which are different in phase, this cycle is repeated, the force is continuously produced, and propulsive force is generated.
