富兰克林轮演示实验的扩展

Extension of the demonstration experiment with Franklin wheel

富兰克林轮转动实验是较好的电学演示实验,而现有的演示方式过于简单.本文扩展了实验的演示方式,分别在平行铝板作用下、单铝板作用下、金属尖端作用下和X射线作用下观察富兰克林轮的转动.

Running of Franklin wheel is a valuable electrical demonstration, while the demonstrating content is too ordinary. In this paper the demonstration of a Franklin wheel is extended. That is, the running of Franklin wheel is studied as the parallel aluminum plates, one single aluminum plate,the top of metal and X ray are chosen as the experiment＇s samples.
