Summary:
Around us, there are many appliances generating electromagnetic noise. The practical measure to shield electromagnetic field is indispensable for our everyday life and protecting our children. An environmental health criterion about magnetic field was published by World Health Organization in last June. But, it is difficult to design the magnetic shield. One of the significant reasons is that all the soft magnetic materials for shield have nonlinear characteristics. The newly found “open-type magnetic shielding method” has features that its shielding performance can be adjusted finely by changing the kinds of materials, dimensions, intervals and so on. Here this study reports the characteristics of open-type magnetic shielding method and its shielding performance by the approaches with linear and nonlinear numerical analyses.
