一、考情分析电磁感应在高考中有着非常重要的位置,是每年的必考内容.这部分内容包括电磁感应现象、磁通量、楞次定律、法拉第电磁感应定律、自感、涡流等考点.电磁感应可以和其他很多知识点结合使题目变得多种多样,也正因如此有时就形成了难度较大的综合题.一般来说在选择题中往往考查磁通量、楞次定律、电磁感应中的图像问题、能量转化问题;在计
First, the test analysis Electromagnetic induction in the college entrance examination has a very important position, is the annual compulsory content.This part includes the phenomenon of electromagnetic induction, magnetic flux, Lenz’s law, Faraday’s law of electromagnetic induction, inductance, eddy current and other test sites. Magnetic induction can be combined with a lot of other knowledge points to make the subject become diversified, it is precisely because of this sometimes form a more difficult comprehensive questions.In general, multiple choice questions are often examined flux, Lenz’s law, electromagnetic induction Image problems, energy conversion problems;
