在电磁感应部分的学习中,我们遇到的难点问题大致包括两方面:一是在闭合回路中,由于导体切割磁感线运动产生电流(发电机),从而引入的对物理量的分析、计算;二是对处于有垂直分量的磁场中的导体通电,引发导体运动(电动机),而进行的分析、计算.牢记原理,理清过程,结合电学、动力 In the learning of the electromagnetic induction part, the difficult problems we encountered generally include two aspects: First, in the closed loop, the current (generator) is generated due to the conductor cutting magnetic induction line motion, which leads to the introduction of the physical quantity analysis and calculation; The second is to energize a conductor in a magnetic field with a vertical component to induce a conductor motion (motor) and perform analysis and calculation. Keep in mind the principle, clarify the process, combine electricity, and power.
