第5届欧洲物理奥林匹克竞赛实验试题1介绍与解答

Introduction and solutions to the experimental question 1 of the 5th European Physics Olympiad experimental exam

第5届欧洲物理奥林匹克竞赛实验试题1为隐藏的导线,试题采用虚拟仿真实验,利用小磁针作为测量装置,由其在不同坐标下的输出转角反推产生磁场隐藏的导线的位置分布.本文较全面地介绍了该试题的内容及其解答,试题涉及电磁学基础知识,能提高考生的空间想象能力,可开设为电磁学黑盒子综合实验.

The question 1 of the 5th European Physics Olympiad Experimental Competition was hidden wire,and this competition was performed virtually as a simulation experiment.The small compass was taken as the measurement device,the position of the hidden wire was deduced by using output angles of compass at different coordinates.The content and solution of experiment 1 of were comprehensively introduced.The questions involved the basic knowledge of electromagnetism,could improve the student’s spatial imagination ability,and could be set up as an electromagnetism black box comprehensive experiment.
