一、感应电流产生的判定例1如图1所示,导体ab沿箭头所指方向运动,试判断下列四种情况中ab有感应电流的是错解AB C错因分析产生感应电流的条件:闭合电路中、一部分导体、做切割磁感线运动,这三个条件必须同时满足,缺一不可.正确解析根据产生感应电流的条件, First, the induced current generated judgment Example 1 As shown in Figure 1, the conductor ab moves in the direction of the arrow, try to determine the following four cases ab is the induction current is the wrong solution AB C error analysis of the induced current conditions: Close the circuit, part of the conductor, to do cutting magnetic induction line movement, these three conditions must be met at the same time, both indispensable.According to the correct analysis of the conditions of the induced current,
