Abstract: The magnetic induction intensity distribution at the center of a ferrite rectangular duct under the external strong magnetic field environment is simulated with Ansys magnetostatic module. Compared with the literature results, analytical solutions and experimental data, simulation results are basically consistent with them. Further numerical simulations also show that the ferrite rectangular duct has a great influence on the overall magnetic field distribution inside it, and it induced magnetic field line distortion and non-uniform magnetic induction intensity distribution are different in different regions. This distribution may have a greater impact on the magnetohydrodynamic effects in the duct.
