Abstract

本实用新型公开了一种电荷相互作用演示器属于教学仪器,特别是电学教学演示仪器。一种电荷相互作用演示器,其特征是:水平底座上装有垂直的带旋转轴芯的支架和固定支架,带旋转轴芯的支架上装有可旋转水平托板托板上放置着带电棒A,固定支架上装有固定托板,托板上放置着带电棒B。使用本实用新型进行演示时,先取下带电棒使其带电,然后分别放置到托板上,当两根带电棒所带电荷极性相同则带电棒A向远离带电棒B方向旋转,说明同性相斥;反之带电棒A向靠近带电棒B方向旋转说明异性相吸引。本实用新型结构简单,易于制作,演示直观。

Description

电荷相互作用演示器
技术领域
本实用新型属于教学仪器,特别是电学教学演示仪器。
背景技术
电荷的相互作用是学生接触电学最早需要掌握的知识之一,演示这一现象一般用吊着的两个带电球,通过看两球互相吸引或排斥来演示相同电荷互相排斥,不同电荷互相吸引。
实用新型内容
本实用新型的目的是提供一种新型电荷相互作用演示器的技术方案。
本实用新型的技术方案为,一种电荷相互作用演示器,其特征是:水平底座上装有垂直的带旋转轴芯的支架和固定支架,带旋转轴芯的支架上装有可旋转水平托板托板上放置着带电棒A,固定支架上装有固定托板,托板上放置着带电棒B。
所述的带旋转轴芯的支架为玻璃试管内装钢条轴芯。
使用本实用新型进行演示时,先取下带电棒使其带电,然后分别放置到托板上,当两根带电棒所带电荷极性相同则带电棒A向远离带电棒B方向旋转,说明同性相斥;反之带电棒A向靠近带电棒B方向旋转说明异性相吸引。
本实用新型结构简单,易于制作,演示直观。
附图说明
附图1为本实用新型的结构示意图。
图中,1.底座,2.带旋转轴芯的支架,3.带电棒A,4.可旋转水平托板,5.带电棒B,6.固定托板,7.固定支架。
