摘要
利用UE-BS-Ⅱ型毕-萨实验仪及其所配备的磁感应强度探测器,采用“正交清零”方法直接测量地磁场水平分量,能够消除垂直于地磁场方向的磁场分量的干扰.改进了传统的测量地磁场的实验方法,具有操作简便、直观等特点,有一定的推广价值.
The UE-BS-Ⅱ Biot-Savart law experimental instrument equipped with a magnetic inductance detector,used the orthogonal clearing method,it had been measured the horizontal components of the geomagnetic field directly.It can eliminate interference with magnetic field components perpendicular to the direction of the geomagnetic field.It improved the traditional methods of the geomagnetic field measurement.It has the characteristics of simple and intuitive operation,so it has a certain promotion value.
