摘　　要：磁偶极子模型被广泛应用于目标物体定位及状态测定应用中,本文讨论了磁偶极子标量模型的推导,并设计了磁传感器模块对其进行验证。在实际位置检测应用中,当检测距离并不远远大于目标体体积的情况下,理想的磁偶极子模型便不能成立,本文基于该标量模型和磁传感器模块,对于在实际应用中理想磁偶极子模型在检测距离变化时的成立条件,并通过Cm实验进行验证,深入研究了磁偶极子理想模型在定位过程中的应用,提出检测磁偶极子模型在距离检测应用中的有效性的检测方法。Magnetic dipole model has been widely used in the application of location detecting. In this paper we discuss the calculation of scalar form of magnetic dipole model and its application limitation. Meanwhile, a magnetic sensor module was developed. Some experiments were carried out to verify the validity of ideal magnetic dipole model in practical application when the detecting distance is not farther than the volume of the object being detected, and Cm experiment was used in the verification. The experiment results indicate the limitation of the ideal magnetic dipole model.
