Abstract
A propulsion system has a unit generating electric current, a unit generating a magnetic field substantially perpendicular to the electric current, and a unit forming a duct 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 to apply a thrust. The unit forming a duct is formed as a closed duct so that the liquid circulates in the duct and does not escape from it.
