随着高考制度的不断改革,高考物理试题由单纯的考查学生对知识的掌握能力慢慢过度为考查考生的知识、能力和科学素养,要求我们学生需要将理解、推理、分析综合、应用数学处理问题及实验能力综合在一起,而不是把某些知识与某种能力简单的对应起来~([1])。其中电磁感应,做为考纲要求的必考内容,构成了高考物理试题的重要部分,在历年所出试题中,既有难度中等的选择题,也有难度较大、综合性较强的计算题,尤其在最近几年更多做为了大型计算去考查高中物理多个部分的知识综合能力。这就要求我们在学习电磁感应时需要既要从根本上掌握基础理论,以应对中等难度的选择题。同时也要求我们去分析并整理归纳出电磁感应的特点、与其它部分的联系、出题方式与题型方法,才能够更好的应对综合性的计算题。
With the continuous reform of the college entrance examination system, physical examination of the college entrance examination by a simple examination of students’ mastery of knowledge slowly over to examine the knowledge, ability and scientific accomplishment of candidates, requiring our students need to understand, reasoning, analysis, application of mathematical processing The problem and the ability to experiment together, rather than some knowledge and ability to simply correspond to a ~ ([1]). Among them, electromagnetic induction, as the required test content of the examination syllabus, constitutes an important part of the physical examination of college entrance examination. Among the examination questions in the past years, there are both multiple-choice questions and difficult, comprehensive ones. Especially in recent years more as a large-scale calculation to examine the knowledge of multiple parts of high school physics comprehensive ability. This requires us to learn electromagnetic induction both need to fundamentally grasp the basic theory, in order to deal with the more difficult choice. At the same time, it also requires us to analyze and sort out the characteristics of electromagnetic induction, and other parts of the link, the title of the questions and methods to be able to better cope with the comprehensive calculation of the problem.
