报告了车辆磁矩的测量以及使用磁通门磁传感器根据过往车辆的磁场驱动照明系统的结果。一辆典型的美国汽车的磁矩约为 200 A-m2（安培米2），而校车的磁矩约为 2000 A-m2。当车辆被建模为力矩为 200 A-m2 的理想磁偶极子时，传感器-车辆几何结构分析的预测结果与系统对汽车响应的观察结果非常吻合。
The measurement of vehicle magnetic moments and the results from use of a fluxgate magnetic sensor to actuate a lighting system from the magnetic fields of passing vehicles is reported. A typical U.S. automobile has a magnetic moment of about 200 A-m2(Ampere-meters2), while for a school bus it is about 2000 A-m2. When the vehicle is modeled as an ideal magnetic dipole with a moment of 200 A-m2, the predicted results from an analysis of the sensor-vehicle geometry agree closely with observations of the system response to automobiles.
