Abstract (en)
It is described a method for manufacturing a permanent magnet, the method comprising: separating, by a separator (107, 207), a mould volume into a first compartment (109, 209) and a second compartment (111, 211); filling a first material (119, 219) into the first compartment (109, 209); filling a second material (121, 221) into the second compartment (111, 211); compacting the first material and the second material, wherein the separator is shaped such that a shape of the first compartment corresponds to a target shape of the magnet.
