大学物理是大学理工科类的一门重要基础课程，工科专业以力学基础和电磁学为主要授课．其中动生电动势的教学是电磁学的重点和难点，学生对该类题目的解答错误较多．本文通过动生电动势典型例题的一题多问以及一问多解的方式对平动切割和转动切割情况下的动生电动势进行详细分析计算，层层递进深入，以此让学生能深刻理解其中所包含的物理以及微积分知识点.

College physics is an important basic course of science and engineering. Engineering majors mainly teach basic mechanics and electromagnetism. Among them, the teaching of motion-induced electromotive force is the focus and difficulty of electromagnetics, and students make many mistakes in answering such questions. In this paper, the motion-induced electromotive force under translational cutting and rotational cutting is analyzed and calculated in detail by means of multiple questions and multiple solutions of typical examples of motion-generated electromotive force. In this way, students can deeply understand the physics and calculus knowledge points.
