地磁场发电演示实验仪的设计

Design of Demo Apparatus for Geomagnetic Field Power Generation

目前初中科学教材《电与磁》章节中,对于地磁场的描述多通过文字说明,内容抽象且验证实验复杂.为了更有效地帮助学生理解地磁场发电,设计一种"地磁场发电演示实验仪",让学生能直观地感受地磁场的存在,了解影响感应电流大小的相关参数,提高学生的课堂注意力,增强课堂教学效果.

At present,the introduction of the geomagnetic field is mostly described in the text,and the content is abstract and the experiment is complicated in the chapter of ＂ Electricity and Magnetism＂ in the textbook of junior middle school science.A ＂geomagnetic field power generation demonstration instrument＂ is designed to enable students to feel the existence of geomagnetic field intuitively and to understand the related parameters that affect the magnitude of induced current.
