In 1600 he published De Magnete in Latin. As lively and entertaining as it was scientifically scrupulous, it summarized everything that had previously been known about electricity and magnetism, founded a new science and earned Gilbert the title of "the father of modern electricity." In it Gilbert explores magnetism and electricity, lodestones, phenomena of magnetism, direction of the earth's magnetic lines of force, variation in the compass, dip, the concept of the earth as a giant magnet, and much else.
This Dover edition is a complete, unabridged reprinting of the definitive English translation of De Magnete prepared by Dr. P. Fleury Mottelay. Dr. Mottelay has added a number of footnotes that explain points that might be obscure to today's readers, who will find in this historically important text invaluable insights into the origins of modern science and physics. Translation by P. F. Mottelay. Biographical introduction. 90 illustrations.
Timeless and collectible, the lectures are essential reading, not just for students of physics but for anyone seeking an introduction to the field from the inimitable Feynman.
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.
In the first part, the fundamentals of magnetism are conveyed for atoms and bulk-like solid-state systems providing a basis for the understanding of new phenomena which exclusively occur in low-dimensional systems as the giant magneto resistance. This wide field is discussed in the second part and illustrated by copious examples.
This textbook is particularly suitable for graduate students in physical and materials sciences. It includes numerous examples, exercises, and references.
See What’s New in the Third Edition
New coverage of applications of magnetism and magnetic materials, especially in magnetic recording
Additional exercises with complete worked-out solutions at the end of the book
Updated references at the end of each chapter
The book adopts an unusual but effectively focused question-answer framework. Each major head is introduced by a question followed by an attempt to answer. This approach maintains attention to the subject matter at hand and clarifies the objective of each section without needless digression. Each chapter also features updated and new exercise problems, accompanied by a solutions manual at the back of the book. This edition gives you an excellent introduction to the key and current theories, practices, and applications of magnetics and magnetic materials.
