Magnetically shielded rooms (MSRs) are vital for experiments that demand an environment with minimal external magnetic interference, such as biomagnetic recordings. Constructed with materials like MuMetal, a nickel-iron alloy, and copper for high magnetic permeability and electrical conductivity, these rooms deflect magnetic fields to ensure a quiet magnetic environment conducive to precise measurements. The benefits of MSRs include: Effective blocking of external magnetic interference. Establishment of a stable, low-magnetic field environment. Newer designs, such as the "Light MuRoom," are lighter, easier to install, and more cost-effective, reducing material costs and installation complexities by around 30% . Additionally, active magnetic shielding systems, like the 'window coil' system, can dynamically adjust the magnetic field within the room to counteract external disturbances in real-time, further enhancing the performance of MSRs.
