摘要： The invention relates to a process of producing a permanent magnet, which comprises extruding a preform (18) to form a plate-shaped permanent magnet (20), in which the preform (18) is extruded in such a way that a dimension of a.cross section of the preform (18) is reduced in an X-direction and enlarged in a Y-direction perpendicular to the X-direction. The invention also relates to a plate-shaped permanent magnet (20) formed by extruding a preform, in which the preform (18) is extruded in such a way that a dimension of a cross section of the preform (18) is reduced in an X-direction and enlarged in a Y-direction perpendicular to the X-direction, whereby said permanent magnet (20) has a strain ratio ε 2 /ε 1 with respect to the preform (18) in a range of 0.2 to 3.5, in which ε 1 is a strain in the direction of the extrusion of the preform (18) and ε 2 is a strain in the Y-direction.
