If using too little MF, the permanent magnet can't be suspended stably. But if adding too much MF, it will impede the movement of the working unit. Considering these two reasons, we chose 6g to 14g MF for the experiments. From the experimental results, it is obvious that the performance of the MFSA with surface textures is distinctly better than that without surface textures. However, the size of the surface texture has little effect on its performance. On the basis of Equation ( ), the change trend of the damping 𝑐 should be consistent with the variation trend of the shear rate 𝛾 . Fortunately, the simulation results of the shear rate 𝛾 in Fig. are in good agreement with the experimental results of the damping 𝑐 in Fig. , as shown in Fig. . Finally, we concluded that the bionic textures change the flow of the MF and generate vortexes in the MF layers, which leads to additional energy consumption. Therefore, the bionic textures significantly enhance the damping efficiency of MFSAs.
