The method provides an electromagnetic assembly in the form of a magnet pole or of a stator packet of an extended stator linear motor for a magnetic levitation train. The assembly includes a sheet stack (8) made of ferromagnetic material and at least one additional component (12,13,14). The sheet stack (8) is assembled from raw magnetic steel sheets and is positioned in a shaping tool. Thereafter by feeding a hardenable mixture into the tool and hardening or hardening out the mixture, the sheets are surrounded with the mixture and connected to each other in a single working step to form the finished sheet stack. In the same working step, the sheet stack (8) is connected to the additional component (12,13,14) and the assembly as a whole is provided with its final electrical, magnetic, mechanical and/or geometric properties.
