In order to verify the effect of surface textures on the damping performance of the MFSA, we fabricated MFSAs with different surface morphology. The circumscribed circle diameter of surface texture 1 was 3 mm, that of surface texture 2 was 2 mm, and that of surface texture 3 was 1 mm. The cylindrical magnet was made of Nd-Fe-B and formed a working unit after absorbing the MF. When external vibration occurred, the working unit leaved the initial equilibrium position, and the inclination angle of the cover provided restoring force to the working unit by compressing the MF to make it reciprocate.
