The first shell portion (8) comprises a magnetic material, and an even outer surface (12) adapted to abut against at least one surface of an electromagnetic device. The first shell portion (8) and the second shell portion (10) differ from each other with respect to material composition and/or material thickness. The amount of magnetic material in the first shell portion (8) is higher than in the second shell portion (10).
