摘要
磁电效应(电磁感应、霍尔效应、磁致电阻效应)是磁场与物质之间的重要的物理效应。只有深入理解电磁学原理,才能进一步学好霍尔传感器。本文针对现有教材状况,强调从理解电磁学中带电粒子在磁场、电场中的运动规律开始,进而深入学习霍尔效应和霍尔传感器。本文还介绍了用形象生动的教学方法,使学生扎实牢固地掌握该知识。
Magneto electric effect (electromagnetic induction, Hall effect and magnetoresistance effect) is an im- portant physical effect between magnetic field and a substance. To learn the Hall effect well, the student must have a deep understanding of the principle of electromagnetics. In response to problems of current textbooks, this paper focuses on a new learning process: understand the law of motion of charged particles in magnetic and electric field ; study Hall effect and Hall sensor. Vivid visual performance is also used in teaching process to enhance students' understanding of such knowledge.
