(57) A method for producing magnets from powdered magnetic alloy. The method comprises
aligning a particle charge of magnet alloy within a container, which aligning may
be achieved by use of a pulsating magnetic field; and consolidating the charge after
alignment to a density in excess of 95% of theoretical density as by cold or hot isostatic
pressing, or a combination thereof.
