For 50 years, Edward M. Purcell's classic textbook has introduced students to the world of electricity and magnetism. The third edition has been brought up to date and is now in SI units. It features hundreds of new examples, problems, and figures, and contains discussions of real-life applications. The textbook covers all the standard introductory topics, such as electrostatics, magnetism, circuits, electromagnetic waves, and electric and magnetic fields in matter. Taking a nontraditional approach, magnetism is derived as a relativistic effect. Mathematical concepts are introduced in parallel with the physics topics at hand, making the motivations clear. Macroscopic phenomena are derived rigorously from the underlying microscopic physics. With worked examples, hundreds of illustrations, and nearly 600 end-of-chapter problems and exercises, this textbook is ideal for electricity and magnetism courses. Solutions to the exercises are available for instructors at www.cambridge.org/Purcell-Morin.

Skillnaden mellan den elektromagnetiska miljö som rådde i början av 1800-talet innan elektricitet och trådlös teknik började användas är som att jämföra mörkret en molnig natt med direkt solljus. Hur har samhället hanterat det när vi samtidigt vet att elektricitet är en avgörande del i kroppens funktioner? EMF handboken tar upp viktiga händelser som Sovjetunionens bestrålning av USA:s ambassad i Moskva med mikrovågor, Världshälsoorganisationens projekt att övertala länder som har lägre gränsvärden att höja dessa, debatten i EU inför beslutet att rekommendera de gränsvärden som vi därefter införde i Sverige. Utgångspunkter för riskutvärderingar som är avgörande för resultatet beskrivs. På nationell nivå har Sverige och Stockholm fått tjäna som exempel. Boken kan ses som en fallstudie hur samhällets hälsoskydd har fungerat. Resultatet är att en tredjedel av befolkningen uppger att de har mer eller mindre besvär de sätter i samband med konstgjorda elektromagnetiska fält.

‘This seminal book...will transform your understanding ...of the environmental and health effects of electricity and radio frequencies’ Paradigm Explorer‘Firstenberg is a pioneer in the sense that Rachel Carson was a pioneer.’ Chellis Glendinning, PhD, author of When Technology Wounds75,000 copies sold! Cell towers, Wi-fi, 5G: Electricity has shaped the modern world. But how has it affected our health and environment?Over the last 220 years, society has evolved a universal belief that electricity is ‘safe’ for humanity and the planet. Scientist and journalist Arthur Firstenberg disrupts this conviction by telling the story of electricity in a way it has never been told before – from an environmental point of view – by detailing the effects that this fundamental societal building block has had on our health and our planet.In The Invisible Rainbow, Firstenberg traces the history of electricity from the early eighteenth century to the present, making a compelling case that many environmental problems, as well as the major diseases of industrialised civilisation—heart disease, diabetes, and cancer—are related to electrical pollution.

Many times through deep history Earth’s magnetic poles have switched places, leaving our planet’s protective shield weaker and life vulnerable to devastating solar storms. The last time it happened was 780,000 years ago, long before humans emerged, but it won’t be long until it happens again. And when it does, will it send us back to the Stone Age?The Spinning Magnet is a fascinating insight into what may lie ahead.From the pivotal discoveries of Victorian scientists to the possibility of solar radiation wiping out power grids, and the secrets of electromagnetism, Alanna Mitchell reveals the truth behind one of the most powerful forces in the universe.

For centuries, electricity was viewed as little more than a curious property of certain substances that sparked when rubbed. Then, in the 1790s, Alessandro Volta began the scientific investigation that ignited an explosion of knowledge and invention, transforming our world. The force that once seemed inconsequential was revealed to be responsible for everything from the structure of the atom to the functioning of our brains. A superb storyteller, Bodanis weaves tales of romance, divine inspiration, and fraud through lucid accounts of scientific breakthrough. The great discoverers come to life in all their brilliance and idiosyncrasy, including the visionary Michael Faraday, who struggled against the prejudices of the British class system, and Alexander Graham Bell, driven to invent by his love for a young deaf student. From the cold waters of the Atlantic, to the streets of Hamburg during a World War II firestorm and the interior of the human body, Electric Universe is a mesmerizing journey of discovery by a master science writer.

A major biography of Michael Faraday (1791–1867), one of the giants of 19th century science and discoverer of electricity who was at the centre of an extraordinary scientific renaissance in London.Faraday’s life was truly inspirational. Son of a Yorkshire blacksmith who moved to London in 1789, he was a self-made, self-educated man whose public life was underpinned by his devotion to a minor Christian sect (the Sandemanians) and to his wife. He was also a fine writer and brilliant lecturer.This book is a passionate exploration of his life, work and times (he was a pioneering scientific all-rounder who also experimented with electromagnetism, techniques for preserving meat and fish, optical glass, the safety lamp, and the identification of iodine as a new element).It will also tell the story of the dawn of the modern scientific age and interweave Faraday’s life with the groundbreaking work of the Royal Institution and other early scientists like Humphrey Davey, Charles Babbage, John Herschel and Mary Somerville.
