摘要
A method of manufacturing a plate-shaped permanent magnet (7) which is to be arranged in an air gap of a core (1) for a transformer or choke coil and which consists of a number of permanent magnetic portions (29) which are made of a metal alloy having a high magnetic remanence and which are magnetized perpendicularly to the plane of the plate. A plate (11) of the alloy is fixed between two insulating foils (13, 15) after which this assembly is arranged on a flat backing (17) and is rolled in two mutually perpendicular directions (25, 27) by means of a cylinder (19) whose outer surface is provided with grooves (23). The plate (11) is thus very simply fractured to form a very large number of portions (29).
