Abstract
A Hall-effect propulsion device including a support body extending between a first end and a second end said body comprising an annular external wall and an annular internal wall arranged coaxially about a longitudinal axis AA′ to form an annular duct, said first end having an annular opening forming an ion outlet;—a magnetic circuit arranged in the annular duct and configured to generate a radial magnetic barrier in the annular duct near the first end of the duct and—at least one magnetic compensation magnetic element arranged in said magnetic circuit and configured to compensate at least a fraction of an absolute value of the residual magnetic moment generated by said magnetic circuit.
