关于电磁感应问题的题型很多,归纳起来大致可以分为如下4类,一类是关于运动学的问题,一类是关于牛顿定律的动力学问题,一类是围绕动量和能量的功能综合问题,最后一类是图象问题,这些问题往往综合出现.值得注意的是,近年来对图象问题的考查在逐步升温,应加强训练.1电磁感应中的 There are many questions about electromagnetic induction problems, which can be roughly divided into the following four categories, one is about kinematics, one is about Newton’s law of dynamics and the other is about the function of momentum and energy synthesis , The last category is the image problem, these problems are often integrated .It is noteworthy that in recent years, the examination of the image problem is gradually warming up, training should be strengthened.1 Electromagnetic induction
