Open-type magnetic shielding method

Abstract

The belief for many years has been that magnetic materials should be arranged without any space between them to achieve a sufficient magnetic shielding effect. However, it was determined that a wall made by aligned strips with sizable gaps could achieve almost the same magnetic shielding effect as a wall using the conventional continuous plate method. In this paper, the new method using aligned strips with gaps is called the open-type magnetic shielding method. The open-type magnetic shielding method allows light and air to pass through walls/boxes providing opportunities to improve a wide range of applications. This study reports the process to devise this open-type magnetic shielding method with some experimental data.
