Abstract
A propulsion system has a substantially tubular housing having an axis, an element generating an electric current, an element generating a magnetic field substantially perpendicular to the electric current, an element forming a duct extending around the axis and arranged so that by interaction of the magnetic field and the electric current a force in a liquid accommodated in the duct is produced and the liquid is moved in the duct around the axis, and at least one insert located in the duct and fixedly connected to a part so that when the liquid is moved it applies a thrust against the insert in a direction around the axis so as to turn the insert and therefore the part around the axis to produce a rotary force which rotates the part around the axis.
