磁浮式反冲运动演示仪的设计与制作

Design and Production of Magnetic Floating Recoil Motion Demonstrator

反冲运动是高中物理教学中的重要内容,教材中通过反冲现象的实验演示来让学生加深对反冲运动的理解,但笔者发现其演示装置存在一些不足.本文介绍了一种磁浮式反冲运动演示仪,该演示仪设计新颖、取材容易、制作简单、操作方便且现象明显,能够在教学中取得良好的效果.

The recoil motion is an important part of high school physics teaching. The experimental demonstration of recoil phenomenon in the textbook allows students to deepen their understanding of recoil motion, but the author finds that there are some shortcomings in the demonstration device. This paper introduces a magnetic floating recoil motion demonstrator, which is novel in design, easy to collect materials, simple to make, and easy to operate, and the phenomenon is obvious, so it can achieve good results in teaching.
