“…One can see that the calculated curves have a more pronounced kink at a lateral deflection of ca ±17 mm compared with the measurements. The reason is that the fluid in the fluid bath of the measurement setup 6 is not confined just to the gap, as it is in the calculation. Thus, the measurement curves are subject to some smoothing effects.…”

“…Filling the airgap with a magnetic fluid, which means that the µ r is increased, lowers the magnetic resistance of the gap and thus that of the whole circuit built up of stator, airgap and rotor. In terms of field theory, 4 the magnetic flux and, as a result, the field strength are enlarged. Both interpretations lead to higher forces, or torque in the case of rotating machines, acting between the magnets.…”

Magneto hydro dynamics (MHD) phenomena exhibit complex behavior. In this paper, a new meshless analysis method employing the magnetic moment method and the particle method is proposed. The particle method is an analysis technique that can be used to calculate fluid motion by the dividing fluid into small particles. The magnetic moment method is an analysis technique in which the magnetic field is calculated by dividing ferromagnetic materials into small elements. In this study, the fluid particles in the particle method are treated as ferromagnetic material elements in the magnetic moment method. Therefore, the proposed coupling method does not require calculation points in the air space, i.e. remeshing of the entire space. In this paper, the proposed method is applied to analyze the behavior of a magnetic fluid under a magnetic field.
