产生感生电流的条件是什么?现行高中物理教材中指出:“不论用什么方法,只要穿过闭合电路的磁通量发生变化,闭合电路中就有感生电流产生.”对这一个知识点,学生在应用它处理问题时一般都分解为两步:先判断电路是否闭合,再判断穿过该电路的磁通量是否变化.二者都满足,电路中就有感生电流产生,缺少任意一条,则不能产生感生电流.总之,电路闭合是产生感生电流的不可缺少的条件之一.
What are the conditions for generating induced currents? Current high school physics textbooks point out: “Whatever method is used, as long as the magnetic flux that passes through the closed circuit changes, there is induced current in the closed circuit.” For this knowledge point, students In the application of it to deal with problems are generally divided into two steps: first determine whether the circuit is closed, and then determine whether the magnetic flux through the circuit changes. Both are satisfied, the circuit has induced current generation, the lack of any one, you can not Induced current is generated. In short, the circuit is one of the indispensable conditions for generating the induced current.
