Simulation study on new susceptibility tester of open-loop magnetic system

In order to explore the influence on magnetic field characteristics of susceptibility tester based on open-loop electromagnetic system,the magnetic field characteristics is numerically simulated by Ansys Maxwell.The magnetic field characteristics of susceptibility tester is visual and symmetrical on the midperpendicular plane of the excitation system;and when the angle of magnetic pole of open-loop magnetic system is 60°,the magnetic field characteristics is more suitable for the testing of susceptibility,the magnetic field strength shows a decreasing trend along the direction between excitation coil and the angle of the magnetic pole.Through the susceptibility testing experiment on Ammonium iron(Ⅱ) sulfate hexahydrate as standard and scientific experiment on Ilmenite iron ore concentrate,the reliability of numerical simulation and working stability of equipment is proved based on Maxwell
