Abstract :
Electrical steel sheet is widely used in constructing chambers and enclosures for magnetic shielding typically at power frequencies. The shielding performance can be affected by forming or joining processes or more often by holes punched through the sheets. This paper presents the effect of holes on the shielding performance of electrical steels at 50 Hz using a recently developed experimental method presented from previous study, and also a 2-D finite element model.
