电磁感应定律的建立及法拉第思想的转变

通过研究《法拉第日记》,并与法拉第公开发表的论文及其他研究资料进行对比分析,可以真实地说明法拉第电磁感应定律的建立过程以及法拉第思想的发展变化情况。法拉第在发现电磁感应现象之前已经预见到了感应电流的瞬时性;法拉第发表的论文存在署名日期提前现象,因此,不能根据论文的署名时间判定法拉第的科学发现和理论的提出时间,法拉第在研究电磁感应现象期间,思想上存在一个从“电紧张态”向“磁力线”的转变过程。力线思想是在这期间形成和确立的。

The Establishment of Electromagnetic Induction Law and Faraday''s Change in Thought

Based on the analysis and study of Faradays Diary and his published articles, this paper elucidates the establishment process of Faraday＇s Electromagnetic Induction Law and his change in thought during this period. This paper points out： Faraday had foreseen the instantaneity of the induced current before his discovery of electromagnetic induction; the date affixed to Faradays article was earlier than the exact time, so people should not judge the formation time of Faraday＇s discoveries and theories according to the signature date in the article; Faraday had a change in thought from ＂electrotonic state＂ to ＂ lines of magnetic force＂ during his research on electromagnetic induction, the thought of lines of force was founded and established.
