Abstract: 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.
