In response to the issues of electronic component damage and signal saturation caused by strong magnetic pulses during the launch of electromagnetic orbital launch weapons,the traditional ap-proach involves utilizing magnetic shielding materials or structures to safeguard the electronic compo-nents.However,these methods often come with high material costs and complex designs.Our study in-troduces a novel magnetic shielding technique that leverages the magnetic shielding effect within the chamber coil to generate a counteracting magnetic field in order to mitigate the impact of strong magnetic pulses on sensor components.Through theoretical derivations,simulations of the coil's magnetic shielding effect,and comparisons with static magnetic field simulation data and experimental results,it is shown that utilizing the coil for magnetic shielding is feasible.Specifically,the tested output voltage signal achieved a shielding effect of 77.4％,confirming that the coil magnetic shielding technology can effec-tively protect sensor components from the impact of strong magnetic pulses.
