Abstract:

The magnetic field generating coils of the low-frequency magnetic field simulation device are large sparse solenoids,whose magnetic field distribution cannot be calculated using the formulas applicable in the case of dense wing.In order to solve this problem,numerical simulation with ANSYS is used to analyze the magnetic flux density and its uniformity.These results are validated by the experimental data.The conclusions of this research provide a direct basis on which to determine the technical indices of the low frequency magnetic field simulation system and magnetic test space.
