The importance of the Maxwell equations in electromagnetism

 Remarkable progress of information society, computers and multimedia equipment, wireless communications, and development of wireless communications and optical networking is something remarkable. In these, which most digital signal processing of signals. For fast processing of large capacity, frequency of use and high-frequency stage, a few hundred MHz to several GHz band has become. 0,1 This digital signal was simply treated as a lumped circuit of the electrical pulse. However, it propagates as an electromagnetic wave through the substrate and finally become the high-frequency, and has been able to design a device to treat the wave. The information and communication, as symbolized by the Internet and mobile phones using radio waves and light waves. Thus, the basis for building the information society, based on Maxwell's equation of "electromagnetism" and require a basic knowledge of, again, "electromagnetism" has reviewed the importance of. 

Electromagnetism, the physical phenomena in the real world is invisible to the naked eye can not be an abstract experience. Such a metaphysical world, and about our ancestors is of great academic genius 200 finished up. In addition, the discovery of electromagnetic waves in the past 100 years. Electromagnetism is equipped with a beautiful finish to a very academic. The beauty of electromagnetism, "in Maxwell's equations" are aggregated to an understanding of electromagnetism, "and understanding of Maxwell's equations, have the freedom to make" an exaggeration to say that it is . 

When you learn to electromagnetism, the learning process and consider two ways. First, few students are easy to understand how you learn the beginner's grade level. Electrical behavior as a starting point for working between the coulombic charge in a vacuum, the effective area of transmitting power "field, the field" as the phenomenon of reification, and theory, electrostatic field, static magnetic field, electromagnetic induction, along the way learn the history of electromagnetism to a kind of Maxwell's equations and systematically. 

Second, that once he learned the basic electromagnetism, and systematically studied electromagnetism and general, as the starting point of Maxwell's equations are suitable for realizing the whole picture, the problem of individual development is how to learn.
