摘要
第3届全国大学生物理实验竞赛基础实验题包括3部分:测量磁针处局域磁场水平分量的大小,测量磁针的磁矩和转动惯量以及地磁场中耦合磁针的运动研究.介绍竞赛试题的实验内容并给出解答,分析了参赛学生的实验考试结果.
The fundamental test problems of the third National College Students’ Physics Experi‐ment Competition contained three sections :measurement of horizontal component of local magnetic field ,measurement of the moment of inertia and magnetic moment of a magnetic needle ,coupled oscil‐lations of a pair of magnetic needles .T his paper introduces the contents of the competition problem , then the solution ,and gives the analysis on the performances of the contestants .
