摘要
为了进一步丰富高中物理实验课及大学物理实验课的课堂教学内容,针对目前物理实验教学中缺少法拉第电磁感应定律定量验证的实验项目等实际情况,我们设计了一种定量测量验证法拉第电磁感应定律的实验项目。这个实验主要是采用均匀改变螺线管中直流电电流强度从而在临近线圈中产生感应电流,建立螺线管中电流强度的变化率与感应电动势之间的定量关系来验证法拉第电磁感应定律。这个实验既可以作为高中物理的实验课教学内容,也可作为理工科大学物理实验课的教学内容,有助于学生直观地理解法拉第电磁感应定律。
In order to further enrich the teaching content of senior high school and college physics experiment course,for the actual situation that there is no the experiment project of quantitative validation for Faraday＇s law of electromagnetic induction in present physics experiment teaching,we designed the experiment project which measures the Faraday＇s law of electromagnetic induction with a quantitative measurement verification method.This experiment adopts the method which changes uniformly the current strength of the direct current in the solenoid to generate the induction current in the adjacent coil,and form the quantitative relation between the rate at which the current intensity changes and the induced voltage in the solenoid to verify Faraday＇s law of electromagnetic induction.The experiment can be the teaching content of physics experiment course in senior high school and university of science and engineering,which contributes students to understand intuitively Faraday＇s law of electromagnetic induction.
