INTRODUCTION

This manual starts from the description of electric and magnetic phenomena as they have been investigated throughout history.

The experiments and laws of Volta, Ampére and Faraday are explained and the main results that led to Maxwell's equations, the real turning point in the study of electromagnetism, are deduced.

These equations are presented in great detail, probing the properties and solutions of the electromagnetic field in the form of electromagnetic waves.

A small handbook on the general properties of wave phenomena is also given.

Finally, the consequences that electromagnetism has had on classical physics and the inconsistencies deriving from it are presented.

A final paragraph is dedicated to the numerous applications of electromagnetic waves without which contemporary technology would not exist.

What is presented in this book requires, at least from the exposition of Maxwell's equations, knowledge of university-level mathematical analysis.

I

ELECTRIC AND MAGNETIC PHENOMENA

Background

––––––––

Electric and magnetic phenomena were unknown to primitive man and the first human civilizations that populated la MesopotamiaEgypt andla Persia.

The first studies on these phenomena date back to ancient Greece by the philosopher Thales towards the sixth century BC.

The name electricity that we all use derives from the properties discovered by Thales of some fossil resins, such as amber, which became electrified by friction, in fact in ancient Greek amber was called "electron".

Some hypothesize that the classic behavior of magnetite in attracting iron filings was previously known in China, where the first rudimentary compass was also built, but this assumption is not supported by archaeological and historical discoveries.

Centuries later, in ancient Rome in the first century after Christ, both Pliny the Elder and Seneca described the properties of amber and investigated the types of lightning.
