Abstract :
In this paper, the effect of the structure of magnetic and conductive layers of an magnetically-shielded room (MSR) on SE is investigated systematically in order to explain the combination effect and establish the optimal design method. In a typical MSR for biomagnetic measurements, multi-layered ferromagnetic materials such as mu-metal (Mu) and conductive materials such as aluminum (Al) are used to shield the room from extremely low-frequency magnetic noises.
