In the Cosserat continuum theory, couple stress and micro rotation of the material are taken into account. To simulate the behaviour of magnetic powder during compaction in magnetic field, we have developed the magneto-Cosserat continuum theory. In this theory, the Maxwell stress that is related to the distribution of magnetic flux density in the powder and particles' easy axes for magnetization are taken into account. By implementing the magneto-Cosserat continuum theory in FEM scheme, it is possible to simulate magnetic alignment in powders with magnetic anisotropy during compaction in an applied magnetic field. In the present paper, we analyze the relationship between the direction of magnetic field and compaction process, such as cross compaction, transverse compaction and isostatic compaction. In the calculation, the directions of the easy axes are given by a set of random numbers. The rotation of the axes is thus calculated at various conditions of applied magnetic field. The results are discussed comparing with those by particle dynamics simulation.
