Abstract

一种旋转磁场模型,在铝盘轴上加装了一个透明的罩子将铝盘罩住,罩子是不随铝盘转动的,即可看见铝盘在旋转磁场作用下转动,又可以把永磁体转动时产生的风隔住,加深了学生对旋转磁场的理解。

Description

旋转磁场模型
所属技术领域:
本实用新型涉及一种教学演示设备,尤其是一种不被学生误认为是风把铝盘带动的教学用旋转磁场模型。 
背景技术:
目前,公知的旋转磁场模型,都是永磁体的旋转后,形成旋转磁场,对应的铝盘由于切割磁力线产生涡流,又由于涡流产生的磁场与旋转磁场作用而使铝盘转动。很多学生则误认为不是旋转磁场的作用使铝盘转动,而错误认为是转动的永磁体产生的风把铝盘带动。 
实用新型内容:
为了克服现有旋转磁场模型的不足,本实用新型提供一种旋转磁场教学模型,它不仅和现有的旋转磁场模型一样使用,而且可以消除学生对旋转磁场的误解,对学生加深理解旋转磁场具有很好的帮助。 
本实用新型解决其技术问题所采用的技术方案是: 
在永磁体对应的铝盘轴上,用一个透明的塑料罩子将铝盘罩住,透明罩子是不转动的,这样即可以看见铝盘在旋转 磁场的作用下,在透明罩子里旋转,又可以将转动的永磁体产生的风隔住。 
本实用新型的有益效果是: 
不增加演示的步骤,非常直观,帮助学生对旋转磁场加深理解。 
附图说明:
下面结合附图和实施例对本实用新型作进一步说明: 
图1是本实用新型的结构示意图 
图中,1、摆把手,2、永磁体,3、铝盘,4、透明罩子。 
具体实施方式:
在永磁体2对应的铝盘3的轴上,加装一个用塑料做成的透明罩子4将铝盘3罩住。透明罩子4是不随铝盘3一起转动的,1为模型的摆把手。
