在解物理习题时,会碰到不少与电磁感应有关的极值问题,从所求的物理量加以分类,这些问题可以分为两类:一类是在电磁感应现象中求某力学量的极值,如求速度、力、角速度等的极值;另一类是在电磁感应现象中求某一电学量的极值,如电流、电功率、电能等的极值。本文以例题的形式介绍如何求解这两类问题。一电磁感应现象中求某力学量极值的问题
In the solution of physical exercises, will encounter a number of extreme issues related to electromagnetic induction, from the physical quantities sought to be classified, these problems can be divided into two categories: one is the phenomenon of electromagnetic induction in the amount of a very mechanical Value, such as speed, force, angular velocity and other extremes; the other is in the electromagnetic induction phenomenon to find an electrical quantity of the extreme, such as current, electric power, power and other extreme. This article describes how to solve these two types of problems in the form of examples. A phenomenon of electromagnetic induction to find a certain amount of mechanics problem
