一、前言将磁流体放置于不均一的磁场中,则液体中的非磁性物质在某一位置上会受到浮力。为使浮力分布达到更为均衡一致,上次报告中曾探讨了磁铁的配置位置,使两块板状铁氧体永久磁铁的 N 极和 S 极对向排列,其夹角为40～50°的条件下,进行了玻璃(比重2.49)和陶瓷(2.24)的分离,并发表了其研究结果。采用铁氧体永久磁铁的装置与电磁铁相比,特点 I. INTRODUCTION By placing a magnetic fluid in an inhomogeneous magnetic field, the non-magnetic material in the fluid is buoyant at a certain point. In order to achieve a more balanced buoyancy distribution, the position of the magnet was discussed in the previous report so that the north pole and the south pole of the two plate-shaped ferrite permanent magnets are aligned with an angle of 40~50 ° , The separation of glass (2.49) and ceramic (2.24) was performed and the results of the study were published. Compared with electromagnets, the ferrite permanent magnet device features
