Electromagnetics Explained (Free PDF)

Description

This book is the result of many years of wondering about and researching the conceptual foundations of electromagnetics. My goal was to write a book that provided the reader with a conceptual understanding of electromagnetics and the insight to efficiently apply this understanding to real problems that confront scientists, engineers, and technicians. The fundamental equations that govern electromagnetic phenomena are those given to us by James Clerk Maxwell, and are commonly known as Maxwell’s equations. Excepting quantum phenomena, all electromagnetic problems can be solved from Maxwell’s equations. (The complete theory of electromagnetics, which includes quantum effects, is quantum electrodynamics, often abbreviated as QED.) However, many people lack the time and/or mathematical background to pursue the laborious calculations involved with the equations of electromagnetism. Furthermore, mathematics is just a tool, albeit a very powerful tool. For many problems, exacting calculations are not required. To truly understand, develop, and apply any branch of science requires a solid conceptual understanding of the material. As Albert Einstein stated, “Physics is essentially an intuitive and concrete science. Mathematics is only a means for expressing the laws that govern phenomena.”* To this end, this book does not present Maxwell’s equations and does not require any knowledge of these equations; nor is it required for the reader to know calculus or advanced mathematics.
