高考分值:6~19分名师指要电磁感应部分是高考的高频考点之一,以电磁感应现象为核心,以法拉第电磁感应定律和楞次定律为重点,主要涉及动力学、电路、图象、能量四种综合问题,涉及力学和电学主要规律的灵活应用,如牛顿运动定律、运动学规律、动能定理、功能关系、能量守恒定律和欧姆定律等,综合性较强。自2009年到2013年以来,新课标卷这部分知识均以选择题的形式出现,2014年新课标II卷以压轴计算题出现,分值明显增加。一、研究《考试说明》,提高复习的针对性2014年物理考纲中对电磁感应的内容要求如下:
College entrance examination scores: 6 ~ 19 points Teacher points to the electromagnetic induction part of the college entrance examination is one of the high-frequency test points to the electromagnetic induction as the core to Faraday’s law of electromagnetic induction and Lenz’s law as the focus, mainly related to dynamics, circuits, maps Elephant, energy, four kinds of comprehensive problems, involving the mechanics and electricity the main laws of flexible application, such as Newton’s law of motion, kinematics law, kinetic energy theorem, functional relationship, law of conservation of energy and Ohm’s law, comprehensive. Since 2009 to 2013, this part of the knowledge of the new curriculums has emerged as a multiple choice question. In 2014, the new curriculums of the new curriculums II appeared on the finale and the scores increased significantly. First, the study of “test description” to improve the relevance of the review 2014 physical examination of the content of the electromagnetic induction requirements are as follows:
