运用有限元分析软件 COMSOL Multiphysics,模拟计算了在80A/m(1 Oe)的磁场中,加入磁集中器后磁场的变化,并讨论了磁集中器的大小、材料磁导率、霍尔元件大小、空间位置等参数对传感器输出参数的影响。计算结果表明,把磁集中器和霍尔元件组合到一起,能够使用传统霍尔元件实现磁场的三维测量,从而可以使其在电子罗盘和地磁导航系统等领域得到广泛的应用。

Finite element analysis software of COMSOL Multiphysics was used to calculate the change of magnetic field after introducing a magnetic flux concentrator(MFC) in an uniform field of 80A/m (1Oe), and the effect of MFC’s dimension, permeability of materials, dimension of Hall elements and space location on output parameters of the sensor was also discussed. The results indicated that three-axis magnetic measurement can be achieved by combining a MFC with Hall elements. This kind of three-axis magnetic sensor may find intensive applications in electronic compass and earth magnetism navigation system.
