Book Description
The book provides both the theoretical and the applied background needed to predict magnetic fields. The theoretical presentation is reinforced with over 60 solved examples of practical engineering applications such as the design of magnetic components like solenoids, which are electromagnetic coils that are moved by electric currents and activate other devices such as circuit breakers. Other design applications would be for permanent magnet structures such as bearings and couplings, which are hardware mechanisms used to fashion a temporary connection between two wires.This book is written for use as a text or reference by researchers, engineers, professors, and students engaged in the research, development, study, and manufacture of permanent magnets and electromechanical devices. It can serve as a primary or supplemental text for upper level courses in electrical engineering on electromagnetic theory, electronic and magnetic materials, and electromagnetic engineering.

Book Description
What is that strange and mysterious force that pulls one magnet towards another, yet seems to operate through empty space? This is the elusive force of magnetism. Stephen J. Blundell considers early theories of magnetism, the discovery that Earth is a magnet, and the importance of magnetism in modern technology.

Book Description
Field theory is an important topic in theoretical physics, which is studied in the physical and physico-mathematical departments of universities. Therefore, lecturers are faced with the urgent task of not only providing students with information about the subject, but also to help them master the material at a deep qualitative level, by presenting the specific features of general approaches to the statement and the solution of problems in theoretical physics. One of the ways to study field theory is the practical one, where the students can deepen their knowledge of the theoretical material and develop problem-solving skills. This book includes a concise theoretical summary of the main branches of field theory and electrodynamics, worked examples, and some problems for the student to solve.The book is written for students of theoretical and applied physics, and corresponds to the curricula of the theoretical courses 'Field theory' and 'Electrodynamics' for physics undergraduates. It can also be useful for students of other disciplines, in particular, those in which physics is one of the base subjects.

Book Description
The mystery of Earth's invisible, life-supporting power Alanna Mitchell's globe-trotting history of the science of electromagnetism and the Earth's magnetic field--right up to the latest indications that the North and South Poles may soon reverse, with apocalyptic results--will soon change the way you think about our planet. Award-winning journalist Alanna Mitchell's science storytelling introduce intriguing characters--from the thirteenth-century French investigations into magnetism and the Victorian-era discover that electricity and magnetism emerge from the same fundamental force to the latest research. No one has ever told so eloquently how the Earth itself came to be seen as a magnet, spinning in space with two poles, and that those poles have dramatically reversed many time, often coinciding with mass extinctions. The most recent reversal was 780,000 years ago. Mitchell explores indications that the Earth's magnetic force field is decaying faster than previously thought. When the poles switch, a process that takes many years, the Earth is unprotected from solar radiation storms that would, among other disturbances, wipe out much and possible all of our electromagnetic technology. Navigation for all kinds of animals is disrupted without a stable, magnetic North Pole. But can you imagine no satellites, no Internet, no smartphones--maybe no power grids at all? Alanna Mitchell offers a beautifully crafted narrative history of surprising ideas and science, illuminating invisible parts of our own planet that are constantly changing around us.

Book Description
Written so as to be understood by the non-technical reader who is curious about the origin of all the electrical and electromagnetic devices that surround him, this history also provides a convenient compendium of information for those familiar with the electrical and magnetic fields. The book moves along at a rapid pace, as it must if it is to cover the enormous proliferation of developments that have occurred during the last hundred years or so.The author has struck a workable balance between the human side of his story, introducing those biographical details that help advance it, and its technical side, explaining theories and "how things work" where this seems appropriate. He also achieves a balance in recounting the discovery of basic scientific principles and their technological applications--the myriad of devices and inventions that utilize energy and information in electromagnetic form.Indeed, one of the important themes of the book is the close and reciprocal relationship between science and technology, between theory and practice. Before approximately 1840, the purely scientific investigations of electrical and magnetic phenomena were largely "ad hoc" and observational, and essentially no technology based on them existed. Afterwards, the scientific explorations became more programmatic and mathematical, and technical applications and inventions began to be produced in great abundance. In return, this technology paid its debt to pure science by providing it with a series of measuring instruments and other research devices that allowed it to advance in parallel.Although this book reviews the early discoveries, from the magnetic lodestone and electrostatic amber of antiquity to Galvani's frog's legs and Franklin's kite-and-key of the 1700s, its major emphasis is on the post-1840 developments, as the following chapter titles will confirm: Early Discoveries--Electrical Machines and Experiments with Static Electricity--Voltaic Electricity, Electrochemistry, Electromagnetism, Galvanometers, Ampere, Biot and Savart, Ohm--Faraday and Henry--Direct Current Dynamos and Motors--Improvements in Batteries, Electrostatic Machines, and Other Older Devices--Electrical Instruments, Laws, and Definitions of Units--The Electric Telegraph--The Atlantic Cable--The Telephone--Electric Lighting--Alternating Currents--Electric Traction--Electromagnetic Waves, Radio, Facsimile, and Television--Microwaves, Radar, Radio Relay, Coaxial Cable, Computers--Plasmas, Masers, Lasers, Fuel Cells, Piezoelectric Crystals, Transistors--X-Rays, Radioactivity, Photoelectric Effect, Structure of the Atom, Spectra.

Book Description
An understanding of the quantum mechanical nature of magnetism has led to the development of new magnetic materials which are used as permanent magnets, sensors, and information storage. Behind these practical applications lie a range of fundamental ideas, including symmetry breaking, order parameters, excitations, frustration, and reduced dimensionality. This superb new textbook presents a logical account of these ideas, staring from basic concepts in electromagnetsim and quantum mechanics. It outlines the origin of magnetic moments in atoms and how these moments can be affected by their local environment inside a crystal. The different types of interactions which can be present between magnetic moments are described. The final chapters of the book are devoted to the magnetic properties of metals, and to the complex behaviour which can occur when competing magnetic interactions are present and/or the system has a reduced dimensionality. Throughout the text, the theorectical principles are applied to real systems. There is substantial discussion of experimental techniques and current reserach topics. The book is copiously illustrated and contains detailed appendices which cover the fundamental principles.
