摘要
对地磁水平分量测量实验加以改进,将其扩充为能够测量亥姆霍兹线圈磁场分布和磁针的转动惯量以及磁针磁矩的实验.使其成为一个综合性较强,适用于开展研究性实验的项目.
Based on the experiment measuring the horizontal component of geomagnetism, a more general experiment is proposed. This new experiment consists of measuring the spatial distribution of magnetic induction of Helmholtz loop, the moment of inertia and magnetic moment of the magnetic needle, So, making this experiment an innovative one for students.
