Essential Electrodynamics: Solutions

Förklaring

This book contains solutions to problems at the end of each chapter of “Essential Electrodynamics”, also by Raymond Protheroe, which is available separately at bookboon.com and provides a concise introduction to this fundamental topic. Starting with Maxwell's equations and conservation laws, it takes a logical step-by-step progression through electromagnetic waves in empty space, dispersive media and in waveguides, and ends with radiation and scattering. The book goes into sufficient detail to explain the important concepts using clear explanations, numerous diagrams, examples and problems.

Förord

This book gives the solutions to the exercises at the end of each chapter of my book “Essential Electrodynamics” (also published by Ventus Publishing ApS). I recommend that you attempt a particular exercise after reading the relevant chapter, and before looking at the solutions published here.

Often there is more than one way to solve a problem, and obviously one should use any valid method that gets the result with the least effort. Usually this means looking for symmetry in the problem – for example from the information given can we say that from symmetry arguments the field we need to derive can only be pointing in a certain direction. If so, we only need to calculate the component of the field in that direction, or we may be able to use Gauss’ law or Ampère’s law to enable us to write down the result. In some of these exercise solutions the simplest route to the solution is deliberately not taken in order to illustrate other methods of solving a problem, but in these cases the simpler method is pointed out.

The solutions to the exercise problems for each chapter of “Essential Electrodynamics” are presented here in the corresponding chapters of “Essential Electrodynamics - Solutions”.

I hope you find these exercises useful. If you find typos or errors I would appreciate you letting me know. Suggestions for improvement are also welcome – please email them to me at protheroe.essentialphysics@gmail.com.
