This book introduces readers to the characteristic features of electromagnetic phenomena in superconductivity. It first demonstrates not only that the diamagnetism in the superconductivity complies with Maxwell’s theory, which was formulated before the discovery of superconductivity, but also that the dominant E-B analogy in the electromagnetism loses perfection without the superconductivity. The book then explores flux pinning, which is responsible for the non-dissipative current in DC, leading to irreversibility in AC. Drawing on Maxwell’s work, it also proves theoretically that if there is no energy dissipation in the superconductivity caused by the break in time reversal symmetry, it contradicts the thermodynamic principle of energy conservation – something that had previously only been proved experimentally. Lastly, the book addresses the longitudinal magnetic field effect, and explains how this phenomenon leads to a new development of Maxwell’s theory. Featuring numerous appendices to help readers understand the methods of derivation of equations, this book offers students and young scientists an introduction to applied superconductivity, especially in the context of power applications. Presenting the characteristic features of electromagnetic phenomena in superconductivity from basic to advanced topics for applications, the book offers a valuable resource for graduate students and researchers studying superconductivity as well as engineers working in electric utility industry.

The main topic of the book are the superconducting dipole and quadrupole magnets needed in high-energy accelerators and storage rings for protons, antiprotons or heavy ions. The basic principles of low-temperature superconductivity are outlined with special emphasis on the effects which are relevant for accelerator magnets. Properties and fabrication methods of practical superconductors are described. Analytical methods for field calculation and multipole expansion are presented for coils without and with iron yoke. The effect of yoke saturation and geometric distortions on field quality is studied. Persistent magnetization currents in the superconductor and eddy currents the copper part of the cable are analyzed in detail and their influence on field quality and magnet performance is investigated. Superconductor stability, quench origins and propagation and magnet protection are addressed. Some important concepts of accelerator physics are introduced which are needed to appreciate the demanding requirements on field quality in large storage rings. The operational experience with the superconducting HERA collider serves as an illustration. Finally superconducting correction coils and practical construction and fabrication methods of accelerator magnets are discussed. The physical and technical principles described in the book are substantiated with a wealth of experimental data on multipoles, persistent- and eddy-current effects, quench performance and much more.

The author introduces the concept that superconductivity can establish a perfect formalism of electricity and magnetism. The correspondence of electric materials that exhibit perfect electrostatic shielding (E=0) in the static condition and superconductors that show perfect diamagnetism (B=0) is given to help readers understand the relationship between electricity and magnetism. Another helpful aspect with the introduction of the superconductivity feature perfect diamagnetism is that the correspondence in the development of the expression of magnetic energy and electric energy is clearly shown. Additionally, the basic mathematical operation and proofs are shown in an appendix, and there is full use of examples and exercises in each chapter with thorough answers.

Superconductivity has become one of the most intensely studied physical phenomena of our times, with tremendous potential to revolutionize fields as diverse as computing and transportation. This book describes the methods, established results, and recent advances in the field. The goal is to present recently developed theoretical models in light of the long-sought aim of achieving the effect at very high temperatures. The book includes a detailed review of various mechanisms, including phononic, magnetic, and electronic models. The authors focus on the phenomenon of induced superconductivity in the high-temperature oxides, particularly the high-transition-temperature cuprates. They also discuss a variety of low-temperature superconducting systems in conventional materials and organics. The book links the crucial experiments with the most current theories, offering a unified description of the phenomenon. All researchers (and graduate-level) students involved with work in superconductivity will find this an invaluable resource, including solid-state and condensed-matter physicists and chemists, and materials scientists.

This iconoclastic book proposes that superconductivity is misunderstood in contemporary science and that this hampers scientific and technological development. Superconductivity is the ability of some metals to carry electric current without resistance at very low temperatures. Properly understanding superconductivity would facilitate finding materials that superconduct at room temperature, providing great benefits to society.The conventional BCS theory of superconductivity, developed in 1957 and awarded the Nobel Prize in 1972, is generally believed to fully explain the lower temperature 'conventional superconductors' but not the more recently discovered 'high temperature superconductors', for which the charge carriers are positive Holes rather than negative electrons. Instead, this book proposes the holistic view that Holes are responsible for superconductivity in all materials. It explains in simple terms how the most fundamental property of all superconductors, that they expel H-fields (the Meissner effect), can be understood with Hole carriers and cannot be explained by BCS. It describes the historical development of the conventional theory and why it went astray, and credits pre-BCS researchers for important insights that were forgotten after BCS but are in fact relevant for the proper understanding of superconductivity.The book's author, Jorge E Hirsch, is a renowned expert in the field of condensed matter physics who has published over 250 articles on the subject. He has developed the theory of 'Hole superconductivity', the focus of this book, over the last 30 years. He is also the inventor of the H-index, a bibliometric measure of scientific impact which, he admits in this book, fails to identify high scientific achievement in the field of superconductivity.
