英文摘要：

Through the finite element simulation software of sensor modeling solution, to verify the rationality of the design of magnetic circuit of sensors and practical in actual experiments. The simulation results show that the sensor＇s unique structure to improve the permeability of ferromagnetic materials are environment, makes the ferromagnetic materials is uniform magnetization, can get clear signal, and can meet the requirements of practical experiments, the magnetic flux values.
