title = "Magnetic Field Adjustment Method for Magnetic Shielding Room Based on Demagnetization",
abstract = "This study presents a method to generate a adjustable residual magnetic field within a magnetic shielding room (MSR), which reduces the complexity and cost of existing magnetic field generation system. By adjusting the DC bias of the demagnetization current, this method influences the magnetization state of the shielding material, thereby enabling adjustment of the residual field. The efficacy of this method has been experimentally validated in a single-layer Permalloy MSR with the size of 340 mm×370 mm×200 mm. The results demonstrate successful generation of residual fields ranging from -400 nT to +400 nT in a single direction, along with a synthetic magnetic field reaching up to 570 nT. The proposed method holds great significance for the widespread adoption and advancement of demagnetization technology.",
