摘要
第22届亚洲物理奥林匹克竞赛实验试题1为磁学黑盒子(Magnetic black box),试题利用智能手机中的磁力计测量磁感应强度随时间的变化,从而研究磁铁在无磁性空心管中的运动及空心管的材料.本文详细介绍了实验试题1的内容,并给出详细解答.
The question 1 of the 22th Asian Physics Olympiad experimental exam was a magnetic black box.The magnetometer in the smartphone was used to measure the change of magnetic induction intensity with time,so as to study the movement of the magnet in the non-magnetic hollow tube and the material properties of the hollow tube.The content of the exam and solutions were introduced in this paper.
