Abstract

It is described a method of manufacturing a permanent magnet, 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) with respect to the cavity (110), iii) placing a magnetic powder (130), comprising a plurality of magnetic particles, into the cavity (110), so that the magnetic particles of the magnetic powder (130) are oriented in the magnet flux (150) to provide an angular distribution of magnetization directions, and iv) forming the permanent magnet from the magnetic powder (130) particles with the oriented angular distribution of magnetization directions. The mold region (120) comprises a magnetic material with a relative magnetic permeability that is larger than the relative magnetic permeability of air, in particular larger than 1.01 µr. Further, a method of providing an electromechanical transducer, a mold (100), and a use of the mold (100) are described.
