Electromagnetism

Basic Laws of Electromagnetism presents to readers an amalgamation of theoretical and practical problems in a single book. The book has been written with the objective to describe the theory behind various concepts in the subject and to explain the various methods of solving practical problems.

The bibliography on electromagnetism is very rich and it may be necessary to justify our effort in writing a new text. The present text arose as a need when lecturing about the subject at Instituto Balseiro, in Bariloche, Argentina. We wanted to have a reference text for the most important topics covered in the course, which would also cover some aspects of interest for the applications of the concepts that the students have learned. follows one in classical mechan­ A course on electromagnetism usually ics. In the latter a brief introduction to the theory of relativity is normally included. During courses on electromagnetism this theory is traditionally pre­ sented again in brief form. This approach has the effect that, unless students later work on related topics, they do not acquire an appropriate knowledge of relativity. In this way, they lose perspective of the importance of one of the most beautiful and fascinating creations of physics in the twentieth cen­ tury. For this reason, we consider the properties of charges, currents and electromagnetic fields in vacuum, highlighting the relativistic transformation properties of each quantity.

This book leads students to learn electromagnetism and then moves to chapters about electric circuits. It aims to give an understanding of electromagnetism which gives a fast way to master the features of circuit elements such as resistors, capacitors, and coils that compose electric circuits. The author provides chapters on electromagnetism and electric circuits separately and gives a chapter explaining the correlation between them in detail.

This book provides the reader with basic tools to solve problems of electromagnetism in thier natural functional frameworks thanks to modern mathematical methods: integral surface methods, and also semigroups, variational methods, etc. well adapted to a numerical approach.
