双层和单层磁屏中置有非导磁体时的屏效问题已有多人进行了研究。作为补充和发展,本文给出了双层和单层磁屏中置有导磁体时的屏效解析及实现优化设计的条件。实验的结果证明了理论解析对工程实践的指导意义。磁屏中置有非导磁体时的屏效解析可作为置有导磁体时屏效解析的特例而导出。
Screen effects of double-layer and single-layer magnetic screens with non-conducting magnets have been studied by many people. As a complement and development, the paper gives the screen resolution and the optimal design conditions of the double-layer and single-layer magnetic shield with the magnetizer placed. The experimental results prove that the theoretical analysis of the guidance of engineering practice. The screen effect when the non-magnetic body is placed in the magnetic screen can be derived as a special case of the screen effect when the magnetic body is set.
