If you are studying physics, chemistry, materials science, electrical engineering, information technology or medicine, then you’ll know that understanding magnetism is fundamental to success in your studies and here is the key to unlocking the mysteries of magnetism....... You can: *obtain a simple overview of magnetism, including the roles of B and H, resonances and special techniques *take full advantage of modern magnets with a wealth of expressions for fields and forces *develop realistic general design programmes using isoparametric finite elements *study the subtleties of the general theory of magnetic moments and their dynamics *follow the development of outstanding materials *appreciate how magnetism encompasses topics as diverse as rock magnetism, chemical reaction rates, biological compasses, medical therapies, superconductivity and levitation *understand the basis and remarkable achievements of magnetic resonance imaging In his new book, Magnetism, Derek Craik throws light on the principles and applications of this fascinating subject. From formulae for calculating fields to quantum theory, the secrets of magnetism are exposed, ensuring that whether you are a chemist or engineer, physicist, medic or materials scientist Magnetism is the book for our course.

Electricity, Relativity and Magnetism: A Unified Text presents the first complete and systematic derivation of the principles of magnetism and electromagnetism from Coulomb’s law and the theory of special relativity alone. Most books on magnetism introduce the subject in terms of experimental observations, as if magnetism were distinct from, albeit associated with, electricity. The topic of relativity is often mentioned, but almost as an afterthought, rather than as a crucial element of the argument. In this new book from Dr Derek Craik, the important links between electricity and magnetism, via special relativity, are emphasized, leading the reader to a more meaningful and profound understanding of the subject. Electricity, Relativity and Magnetism: A Unified Text gives a simple and brief review of Einstein’s special theory of relativity, emphasizing force transformations. An outline of electrostatics, Coulomb’s law and its consequences, is also given and is shown to lead to the basis of magnetostatics. Time-dependent electromagnetic effects are introduced naturally via the transformation equations for fields and for potentials, and Maxwell’s equations are systematically derived. Magnetic dipoles and magnetization are shown to arise on transforming electric dipoles and polarizations. The author next discusses the application of the theory to practical magnetic calculations, and finally goes on to introduce the quantum theory of magnetism. The concept of spin is introduced, leading to spin statics and magnetic ordering, and spin dynamics and resonances. An account of crystal field theory is included. All whose work and research involves the understanding of magnetic phenomena will find Electricity, Relativity and Magnetism: A Unified Text an invaluable resource which will enhance and deepen their understanding of the subject.
