摘要： An elongated ferrite structure of barium or strontium ferrite is constructed of zones in which the ferrite materials are made to have different magnetic properties, the ferrite material located in the region of the highest demagnetizing stress placed thereon when incorporated into a dynamo electric machine, due to the armature reaction, being made of ferrite of high coercive force, the remaining regions of the magnet structure being made of ferrite material having high remanence, the entire structure being, preferably, a single element.
