Abstract: A jetting device includes: a fluid chamber connected to a nozzle and containing an electrically conductive liquid to be jetted out through the nozzle; a magnetic field generator arranged to create a magnetic field in the fluid chamber; a pair of electrodes contacting the electrically conductive liquid in the fluid chamber; and a controller arranged to control a flow of an electric current through the electrodes and the electrically conductive liquid. The magnetic field generator is arranged to create a rotating magnetic field in the fluid chamber.
