The Design Of Three-axis Magnetic Field Simulation Device

The static magnetic field is more and more widespread in modern industrialproduction and scientific experiment. In different environments, the strength of themagnetic field distribution and the magnetic field are not same, and thus differentmagnetic field generating means are required. Especially with the diversity ofdevelopment of the test, not only the traditional large-scale magnetic field simulationapparatus are used, but also the small, light weight, easy handling of the magneticfield apparatus demand is also increasing.This paper introduces a simulator which can simulate the dynamic magnetic fieldenvironment. The institute of the system, coil structure, power and magnetometerparameters, control method and calibration method of this simulator are detaileddescribed in this paper. The simulator can receive the instruction of the host computer,via closed-loop control, programmable power supply to achieve the simulation of themagnetic field environment.
