一、电磁感应中的电路问题解决此类问题的基本思路是:解决电磁感应电路问题的关键是把电磁感应的问题等效转换成稳恒直流电路.具体讲有这样的三步:(1)确定电源.切割磁感线的导体或磁通量发生变化的回路将产生感应电动势,则该导体或回路就相当于电源,利用法拉第电磁感应定律求感应电动势的大小,利用右手定则或楞次定律判
A circuit problem in electromagnetic induction The basic idea to solve this kind of problem is: The key to solving the problem of electromagnetic induction circuit is to convert the electromagnetic induction problem equivalent into a stable DC circuit. Specifically, there are three steps: (1) Determine the power supply. Cut the magnetic induction line or the magnetic flux will change the circuit will produce the induced electromotive force, the conductor or circuit is equivalent to the power supply, the use of Faraday’s electromagnetic induction law to find the size of the induced electromotive force, use the right-hand rule or Lenz’s law
