A method of producing a permanent magnet includes forming a magnetisable workpiece by additive manufacturing and forming the permanent magnet by partitioning the magnetisable workpiece. The additive manufacturing includes steps of forming a first powder layer by depositing a first powder, the first powder being ferromagnetic; forming a first workpiece layer of the magnetisable workpiece by irradiating a predetermined first area of the first powder layer by means of a focused energy beam to fuse the first powder in the first area; and repeating the above steps multiple times to form further workpiece layers of the magnetisable workpiece. The permanent magnet is formed by partitioning the magnetisable workpiece, where an exposed surface of the permanent magnet formed by the partitioning is non-parallel to the first workpiece layer, and where the permanent magnet produces an external magnetic field having a magnetic field strength of at least 1 kA/m.
