分析近三年的各地高考试卷不难发现,近年来高考对电磁感应的考查,主要集中在电磁感应与其他知识相综合的考查上,这一点在理综试卷中显得尤为明显.这部分内容的考查多以选择题和计算题的形式出现,而在实验题中出现的少.试题的难度以中等难度为主,容易题和高档题出现的也很少.另外涉及动生电动势的考题比涉及感生电动势的要多.与其他知识综合方面,主要与电路知识、力学知识、能量知识和图象知识进行综合.
It is not difficult to find that in the past three years, it has been found that the examination of electromagnetic induction in the college entrance examination in recent years mainly focuses on the examination of electromagnetic induction and other knowledge. This is particularly evident in the comprehensive examination papers. Examinations are mostly in the form of multiple-choice questions and calculation questions, but there are few questions in the experiment questions. The difficulty of the questions is mainly medium-level difficulty, and the easy-to-use questions and high-grade questions are rare. In addition, the examination questions involving the electromotive force ratio involve Inducing electromotive force is much more. Integrating with other knowledge, mainly with circuit knowledge, mechanics knowledge, energy knowledge and image knowledge.
