The Research Of Complicated Problems About The Electromagnetic Field Theory Teaching

After comprehensive study of the teaching of electromagnetic field theory, we found that there still exited some problems in the physical teaching in spite of some new developments. For example, the teaching material covering relative limited knowledge has been out of date; some equivocal problems are required to be explained reasonably from the higher level. So the all-important problems in the physical teaching are how to imply new knowledge and new concept in the teaching process, and how to cultivate the scientific accomplishment and the ability of creation. In order to optimize the teaching of electromagnetic field theory, the thesis will analyze and discuss several typical complicated problems about the electromagnetic field.In 1864, Maxwell summarized the rule of electromagnetic field as the Maxwell equation set, and predicted the presence of electromagnetic waves, which accelerated the discovery of electromagnetic waves.It is a interested topic about the relativistic motion for a charged particle in electromagnetic field, in four dimensional Minkowski space ,this paper discusses a method to solve equation of relativistic motion for a charged particle in uniform electromagnetic field.The confinement of electric charges in the electro-magnetic field has been studied in detail, which will not only benefit development of electro-magnetic field theory, but also provide a visual model and a phenomenological explanation of the confinement of quarks in the internal structure of basic particles.In the past, we only regarded the confinement of electric charges as an assistant function describing the magnetic field, But with the discovery of Aharonov-Bohmeffect, it influences the motion of the charged particle in deed just as E and B,onthe other hand, applying the confinement of electric charges in some certain conditions is more effective and more convenient..The reasonable system of electro-magnetic field theory had been established by connecting the model mathematic method with the model physics concept, which avoided the difficulty of classical field theory.
