About this course
Electromagnetic phenomenon is one of the most important phenomena in nature, which has always been an important issue for ancient scientists or the present scientists. For the students of electrical and electronic information engineering, the core of their major courses is the embodiment of electromagnetic phenomena in a specific range and under specific conditions.
Using the qualitative process and quantitative method to analyze electromagnetic phenomena is the necessary professional knowledge and skills for an electrical engineering student. The electromagnetic field analyzing principle and method also are the theoretical base of electrical application disciplines. The electromagnetic field theory is the theoretical base of electrical, electronic and information technology, the most essential description of macro electromagnetic phenomenon, the" key” to open the door of electrical engineering castle.
Electromagnetic Field is the prerequisite course for Electrical Machine, Electrical Engineering Theory and other specialized courses of electrical engineering.
Electromagnetic Field needs the prerequisite courses such as Advanced Mathematics, College Physics, Vector Analysis and Field Theory. The course asks the students to establish the viewpoint of "field" and provide theoretical and technical support for the follow-up professional courses. The course would lead students to understand the theorem and the physical meaning of the Maxwell equations and mathematical expressions, to master the vector analysis method of basic electromagnetism phenomenon, to describe the essential physical concept of electromagnetic field based on summarizing the basic law of experiment.
After learning this course, students will have completely knowledge about the theorem and the physical meaning of the Maxwell equations and mathematical expressions. It includes the static and time-varing electromagnetic fields. The common question representation methods and solving methods for electromagnetic field are known. The main objective is to lay the ground work for future intensive study in electromagnetic field.
