摘要: We have designed four sets of multi-layer nested magnetic shields. External diameters for the individual shielding layers range from 3.3 cm to 5.3 cm. The shields are tested by fluxgate magnetometer separately. result experiment is in excellent agreement with theoretical calculations. compact made high-permeability material compared. largest factor measured was 32.3 dB a set three cylinders (Set 2). two spheres structure 4) has uniform region (12 mm). one shell sphere and cylinder 3) achieve best trade-off between factor.
