涡流不同于我们通常所说的闭合回路中的感应电流,是当大块导体处于变化的磁场中时导体中形成的感应电流。教材中关于涡流的实验相当少且不成系统,本文设计了关于涡流效应的四个探究实验,通过对实验原理的解释,对实验现象的探究,使学生对导体的涡流效应有更深刻的认识。 The eddy current is different from the inductive current in the closed loop, which we usually refer to, as the induced current in the conductor when the bulk conductor is in a changing magnetic field. The textbook on the eddy current experiment is relatively small and not systematic, this paper designed four on the eddy current test experiment, through the interpretation of the experimental principle, the study of the experimental phenomena, so that students have a more profound understanding of the eddy current effect of the conductor.
