Description

  The present invention relates to a magnetic propulsion device that uses a magnetic force applied by a permanent magnet as a propulsive force.

There has been a propulsion device that uses magnetic force. For example, in a linear motor car, a vehicle is propelled by a magnetic force acting on a conductive magnet of the vehicle by causing a current to flow through a ground propulsion coil to generate a magnetic field. Moreover, as another propulsion device using magnetic force, there is one that contributes to energy saving by suppressing input power as much as possible (Patent Document 1). However, such a propulsion device requires electrical energy, which causes cost problems and environmental problems.
