ABSTRACT:
Ink droplets for ink-jet printing are formed in a conductive, ink by flowing ink having a ion magnetic susceptibility between the poles of a pulsed electro-magnet thereby periodically inducing eddy currents in bodies of the ink which oppose ink flow and stimulate perturbations of an ink stream having an orifice so that discrete droplets of ink are formed at a uniform distance from the orifice.
