Elektricitet och magnetism

‘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.

In this new edition of the standard undergraduate textbook on electricity and magnetism, David Griffiths provides expanded discussions on topics such as the nature of field lines, the crystal ambiguity, eddy currents, and the Thomson kink model. Ideal for junior and senior undergraduate students from physics and electrical engineering, the book now includes many new examples and problems, including numerical applications (in Mathematica) to reflect the increasing importance of computational techniques in contemporary physics. Many figures have been redrawn, while updated references to recent research articles not only emphasize that new discoveries are constantly made in this field, but also help to expand readers' understanding of the topic and of its importance in current physics research.

The story of two brilliant nineteenth-century scientists who discovered the electromagnetic field, laying the groundwork for the amazing technological and theoretical breakthroughs of the twentieth centuryTwo of the boldest and most creative scientists of all time were Michael Faraday (1791-1867) and James Clerk Maxwell (1831-1879). This is the story of how these two men - separated in age by forty years - discovered the existence of the electromagnetic field and devised a radically new theory which overturned the strictly mechanical view of the world that had prevailed since Newton's time.The authors, veteran science writers with special expertise in physics and engineering, have created a lively narrative that interweaves rich biographical detail from each man's life with clear explanations of their scientific accomplishments. Faraday was an autodidact, who overcame class prejudice and a lack of mathematical training to become renowned for his acute powers of experimental observation, technological skills, and prodigious scientific imagination. James Clerk Maxwell was highly regarded as one of the most brilliant mathematical physicists of the age. He made an enormous number of advances in his own right. But when he translated Faraday's ideas into mathematical language, thus creating field theory, this unified framework of electricity, magnetism and light became the basis for much of later, 20th-century physics.Faraday's and Maxwell's collaborative efforts gave rise to many of the technological innovations we take for granted today - from electric power generation to television, and much more. Told with panache, warmth, and clarity, this captivating story of their greatest work - in which each played an equal part - and their inspiring lives will bring new appreciation to these giants of science.

The third section covers several important aspects of a phased array design including array tolerance analysis. Phased Array Antennas includes information on sample topics such as: Scan characteristics of a pencil beam array in light of gain, grating lobe, beam-width beam squint, and mitigation of beam-squint issueScan characteristics of array-fed confocal reflectorsThe relationship between a Floquet mode and observable array parameters such as active element pattern, mutual coupling, scan blindnessGeneralized Scattering Matrix (GSM) approach to analyze multilayer array structures, including stacked patches, ring-slot radiators, FSS and screen polarizersFinite array modeling including the edge effects on input match and radiation patternCharacteristics of step and multi-flared horns for enhanced radiation efficiencyFrequency selective surfaces, meander line polarizer screens, printed reflect-array antennas, metamaterial and their fundamental propertiesBeam formers, beam shaping algorithms, array system analysis and array tolerance analysisPhased Array Antennas is an excellent reference for advanced graduate students who are seeking professional careers in antenna and microwave engineering as well as antenna design engineers and technical consultants seeking to understand and apply the latest Floquet model for analyzing practical phased array structures.

This textbook gives a basic introduction to theoretical physics. It deals with mechanics, electrodynamics, theory of relativity, quantum mechanics and statistical physics, thus covering all the standard disciplines of theoretical physics in a single volume.

The third volume in Leonard Susskind's one-of-a-kind physics series cracks open Einstein's special relativity and field theoryIn the first two books in his wildly popular The Theoretical Minimum series, world-class physicist Leonard Susskind provided a brilliant first course in classical and quantum mechanics, offering readers not an oversimplified introduction, but the real thing - everything you need to start doing physics, and nothing more. Now, thankfully, Susskind and his former student Art Friedman are back, this time to introduce readers to special relativity and classical field theory. At last, waves, forces and particles will be demystified. Using their typical brand of relatively simple maths, enlightening sketches and the same fictional counterparts, Art and Lenny, Special Relativity and Classical Field Theory takes us on an enlightening journey through a world now governed by the laws of special relativity. Starting in their new watering hole, Hermann's Hideaway, with a lesson on relativity, Art and Lenny walk us through the complexities of Einstein's famous theory. Combining rigor with humour, Susskind and Friedman guarantee that Special Relativity and Classical Field Theory will become part of the reader's physics toolbox.

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 text introduces the key concepts of superconductivity, superfluidity and Bose-Einstein condensates, three extremely important and rapidly developing fields of research which are closely related intellectually, in spite of their very different physical systems. The topics are developed alongside the necessary mathematical tools and no previous knowledge of quantum many-body theory is necessary.

This book is a comprehensive guide to computer simulations for Electromagnetic Compatibility (EMC) in electronic systems. It brings together the key domains a simulation engineer must master—circuit simulation, field simulation, numerical methods, and expertise in EMC phenomena—to effectively model, analyze and predict the EMC of electronic systems.Using classical EMC scenarios as case studies, the book demonstrates how simulation supports design decisions and performance predictions, with a focus on industrial applications and efficient simulation workflows. A consistent modeling approach is followed throughout: every EMC problem is decomposed into source, coupling path, and sink, with appropriate modeling techniques introduced for each part.Early chapters introduce circuit-level models and field simulation methods. As the book progresses, more advanced numerical methods and simulation workflows are introduced, enabling the simulation of complex EMC challenges. In the later sections, simulations based on standardized EMC test setups are explored. These typically involve large, computationally demanding models—here, strategies for model simplification and their impact on results are examined.Key Features:• A complete framework for EMC simulation using combined circuit and field simulation• Step-by-step guidance on how to virtually analyze and predict the EMC of electronic systems• Practical, industry-related examples that reflect common challenges faced by EMC engineers• More than 150 simulation models based on CST Studio Suite are available through Springer’s GitHub repository

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.

The Earth's magnetic field has existed for hundreds of millions of years, far longer than life has existed on Earth, and affects our lives in many ways. We can use it to orient buildings and navigate across unmarked territory. Moreover, it protects us from harmful radiation from space.Intended as an introductory guide for non-specialist readers, this book describes the historical importance of the Earth's magnetic field and its role in protecting the planet from harmful high-energy radiation from the Sun. With explanations of underlying physics of processes and references to original scientific works, the reader can explore the Earth's magnetic field and the various ways in which geomagnetics are used and measured, including the analysis of modern satellite-based investigations and the effects of solar activity on the geomagnetic field.

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.

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.
