Simulation validation based on emission coil of three-axis square Helmholtz magnetic source

Abstract In electromagnetic detection, the received signal strength is largely determined by transmitter’s strength. Therefore, it necessary to select and design transmitting coil meet requirements of launching system. To obtain better-transmitting coils, Maxwell used establishing square toroidal models for calculation compare magnetic field intensity uniformity. cope with exploration in a complex environment, model three-axis Helmholtz established. The simulation results verify that has higher emission under same excitation condition, which suitable exploration.
