法拉第电磁感应定律是电磁感应现象的基本规律,其内容抽象、内涵丰富,涉及到的现象纷繁复杂,限于中学阶段学生的理解和数学知识水平,虽然教材对于许多内容进行了删减,但许多学生在初次接触时往往仍是背公式、记结论,缺乏对定律的深刻认识,做题时只是凭感觉,影响了后阶段对于电磁场等知识的学习。为此,笔者在教学中尝试借助变压器创
Faraday’s law of electromagnetic induction is the basic law of electromagnetic induction. Its content is abstracted and rich in connotation. The phenomena involved are numerous and complicated. It is limited to students’ understanding and knowledge of mathematics in middle school. Although many materials have been deleted from textbook, many students In the initial contact is often still the formula, remember the conclusion, the lack of a deep understanding of the law, when the problem is just by feeling, affecting the latter stages of the electromagnetic field and other knowledge learning. To this end, I try to teach in the use of transformers
