Method for manufacturing permanent magnet by using magnetic material mold

A method of manufacturing a permanent magnet is described, the method comprising: i) providing a mold (100) wherein the mold (100) comprises a cavity (110) and a mold region (120) around the cavity (110), ii) establishing a magnetic flux (150) relative to the cavity (110), ii) placing a magnetic powder (130) comprising a plurality of magnetic particles into the cavity (110) such that the magnetic particles of the magnetic powder (130) are oriented in the magnetic flux (150) to provide an angular distribution of magnetization directions, and iv) forming a permanent magnet from particles of magnetic powder (130) having a directed angular distribution of magnetization directions. The mold region (120) comprises a magnetic material having a relative permeability greater than the relative permeability of air, in particular greater than 1.01 [mu] r. In addition, a method of providing an electromechanical transducer, a mold (100) and a use of the mold (100) are described. 描述了一种制造永磁体的方法，该方法包括：i)提供模具(100)，其中，模具(100)包括
