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.

Magnetism is a strange force, mysteriously attracting one object to another apparently through empty space. It has been claimed as a great healer, with magnetic therapies being proposed over the centuries and still popular today. Why are its mysterious important to solve? In this Very Short Introduction, Stephen J. Blundell explains why. For centuries magnetism has been used for various exploits; through compasses it gave us navigation and through motors, generators, and turbines it has given us power. Blundell explores our understanding of electricity and magnetism, from the work of Galvani, Ampere, Faraday, and Tesla, and goes on to explore how Maxwell and Faraday's work led to the unification of electricity and magnetism, thought of as one of the most imaginative developments in theoretical physics. With a discussion of the relationship between magnetism and relativity, quantum magnetism, and its impact on computers and information storage, Blundell shows how magnetism has changed our fundamental understanding of the Universe. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

The aim of this advanced textbook is to provide the reader with a comprehensive explanation of the ground state configurations, the spin wave excitations and the equilibrium properties of spin lattices described by the Ising–Heisenberg Hamiltonians in the presence of short (exchange) and long range (dipole) interactions. The arguments are presented in such detail so as to enable advanced undergraduate and graduate students to cross the threshold of active research in magnetism by using both analytic calculations and Monte Carlo simulations. Recent results about unorthodox spin configurations such as stripes and checkerboards should then excite theoreticians in the field of magnetism and magnetic materials research. Contents:Magnetic HamiltoniansSpin Waves in FerromagnetsInteracting Spin Waves in FerromagnetsFeynman Diagrams Expansion in FerromagnetsTwo-Magnon Bound States in FerromagnetsPerturbation Theory in Planar FerromagnetsSpin Waves in Non-Collinear SystemsSpin Waves in MultilayersSpin Waves in Systems with Long Range InteractionLong Range Interactions in 2D Systems Readership: Students and professionals interested in the fields of theoretical magnetism and magnetic material research. Keywords:Spin Waves;Many-Body Theory in Magnetism;Two-Magnon Bound States;Helix Spin Configurations;Stripe and Checkerboard Spin ConfigurationsKey Features:Many-body theory applied to magnetic insulators: the Green function approach is compared to the Feynman diagram expansionTwo spin wave deviations from clusters to thermodynamic limitStripe and checkerboard configurationsReviews: “The book combining the modern problems of statistical mechanics, directed to the study of magnetic excitations in different systems, with strict mathematical statement and the solution of the corresponding problems will be very useful for undergraduate and graduate students studying the magnetism problems, and also for theoreticians researching magnetism and magnetic materials.” Zentralblatt MATH

For the general public, magnetism often seems more the province of new age quacks, movie mad scientists, and grade-school teachers than an area of actual, ongoing scientific inquiry. But as Ronald T. Merrill reveals in Our Magnetic Earth, geomagnetism really is an enduring, vibrant area of science, one that offers answers to some of the biggest questions about our planet’s past—and maybe even its future.
