N2 - Considering the technical requirements of the space physical environment simulation system, a square Helmholtz coil was built by a pair of axis symmetric rectangular coils which had the same turns, side length, height and thickness, based on the principle of Helmholtz coils. Combining with the constant current source and MCU control technology, the electromagnetic field simulation system was designed. Adopting finite element analysis software ANSYS Workbench, the magnetic field distribution of the square Helmholtz coil was simulated, and the emphasis of the study was on the electromagnetic field distribution of the coil X-axis, Y-axis and near the surface of the coil. Based on the analysis results, the structure parameters of the square Helmholtz coil were designed. The magnetic flux density of 12 key points was measured inside the designed coil. The results show that the magnetic flux density and uniformity of the magnetic field inside the coil could satisfy the requirements of the space environmental simulation systems.
