Electricity and Magnetism


Book Description

This book is a very comprehensive textbook covering in great depth all the electricity and magnetism. The 2nd edition includes new and revised figures and exercises in many of the chapters, and the number of problems and exercises for the student is increased. In the 1st edition, emphasis much was made of superconductivity, and this methodology will be continued in the new edition by strengthening of the E-B analogy. Many of the new exercises and problems are associated with the E-B analogy, which enables those teaching from the book to select suitable teaching methods depending on the student’s ability and courses taken, whether physics, astrophysics, or engineering. Changes in the chapters include a detailed discussion of the equivector-potential surface and its correspondence between electricity and magnetism. The shortcomings of using the magnetic scalar potential are also explained. The zero resistivity in a magnetic material showing perfect diamagnetism can be easily proved. This textbook is an ideal text for students, who are competent in calculus and are taking physics, astrophysics, or engineering at degree level. It is also useful as a reference book for the professional scientist.

Book Description

Notes on Recent Researches in Electricity and Magnetism J. J. Thomson Excerpt from Notes on Recent Researches in Electricity and Magnetism, Intended as a Sequel: To Professor Clerk-Maxwell's Treatise on Electricity and Magnetism IN the twenty years which have elapsed since the first appearance of Maxwell's Treatise on Electricity and Magnetism great progress has been made in these sciences. This progress has been largely - perhaps it would not be too much to say mainly - due to the influence of the views set forth in that Treatise, to the value of which it offers convincing testimony. In the following work I have endeavoured to give an account of some recent electrical researches, experimental as well as theoretical, in the hope that it may assist students to gain some acquaintance with the recent progress of Electricity and yet retain Maxwell's Treatise as the source from which they learn the great principles of the science. I have adopted exclusively Maxwell's theory, and have not attempted to discuss the con sequences which would follow from any other view of electrical action. I have assumed throughout the equations of the Electro magnetic Field given by Maxwell in the ninth chapter of the second volume of his Treatise.

I have adopted exclusively Maxwell's theory and have not attempted to discuss the consequences which would follow from any other view of electrical action. I have assumed throughout the equations of the Electromagnetic Field given by Maxwell in the ninth chapter of the second volume of his Treatise. The first chapter of this work contains an account of a method of regarding the Electric Field, which is geometrical and physical rather than analytical. I have been induced to dwell on this because I have found that students, especially those who commence the subject after a long course of mathematical studies, have a great tendency to regard the whole of Maxwell's theory as a matter of the solution of certain differential equations, and to dispense with any attempt to form for themselves a mental picture of the physical processes which accompany the phenomena they are investigating.
