摘要
由于空气阻力等原因,单摆无法保持周期性摆动。为解决单摆在科普场馆中的展示难题,作者研发了两种依靠永磁体和电磁铁提供磁力的装置。观众可以通过互动体验,感受机械传动的魅力,理解背后的科学原理,同时也为相关展品的开发与设计提供新的思路。
Single pendulum cannot maintain periodic motion due to air resistance and other reasons. In order to solve the problem of displaying single pendulum in popular science venues, two kinds of devices were developed to realize periodic swing of single pendulum by magnetic force provided by permanent magnet and electromagnet. Visitors can enjoy the charm of mechanical transmission and understand the scientific principles behind the devices through the interactive experience with the exhibits. The exhibits also provide new ideas for design of new relevant exhibits.
