电磁感应的图象问题是高考的热点问题。在高三一轮复习,二轮复习的参考用书和物理卷上,经常会遇到一道关于电磁感应图象的习题。通过网上查阅和阅读有关参考用书后,发现它们给出的参考解析基本一致,但是解答的严密性不足,有的地方值得推敲与商榷。若在原题的基础上,再深入探究,一题多解,适当拓展,其教学效果将更好。 The electromagnetic induction image problem is a hot issue in college entrance examination. In the third year of review, two review books and physical volumes, often encounter a problem on the electromagnetic induction images. Through the Internet access and read the reference books, found that they are given the same reference resolution, but the lack of tight answers, some places worth considering and open to question. If the original title, based on further exploration, a problem more than solution, appropriate expansion, the teaching effect will be better.
