dc.descriptionWe consider a ferrofluid cylinder, that is rotating with constant rotation frequency Ωe_z as a rigid body. A homogeneous magnetic field H_0 e_x is applied perpendicular to the cylinder axis e_z. This causes a nonequilibrium situation. Therein the magnetization M and the internal magnetic field H are constant in time and homogeneous within the ferrofluid. According to the Maxwell equations they are related to each other via H = H_0 - M/2. However, H and M are not parallel to each other and their directions differ from that of the applied field H_0. We have analyzed several different theoretical models that provide equations for the magnetization in such a situation. The magnetization M is determined for each model as a function of Ωand H_0 in a wide range of frequencies and fields. Comparisons are made of the different model results and the differences in particular of the predictions for the perpendicular components H_y =-M_y/2 of the fields are analyzed.
