METHOD FOR IMPROVING THE EFFECTIVENESS OF A MAGNETIC FIELD FOR MAGNETIZING PERMANENT MAGNETS

摘要

A method for increasing the coercive force of a permanent magnet produced by a given magnetizing field. The magnet is subjected to the magnetizing field with the initial position of the magnet being no greater than an angle theta of +/-45 DEG formed between a predetermined direction of magnetization of the magnet and the direction of the applied magnetizing field. The magnet and/or magnetizing field are moved in at least a single plane through the angle theta which can range up to +/-45 DEG . Such movement is terminated with the magnet in a position in which its predetermined direction of magnetization is substantially parallel to the direction of the magnetizing field.
