Electricity and Magnetism New Formulation by Introduction of Superconductivity

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.

Prof. Dr. Teruo Matsushita has studied flux pinning and related electromagnetic phenomena in superconductors for 48 years. The first research field includes theoretical calculation of elementary pinning force of specific pinning centers and estimation of the pinning force density as a function of the elementary pinning force and number density. In the latter research field he establish the critical state theory that supports the well-known critical state model by using the first principles of minimizing the free energy in the reversible state followed by development to the irreversible state. The theoretical analyses of the longitudinal field problem and the effect of flux creep in high-temperature superconductors are also included in the latter category.  He is a member of The Institute of Electrical Engineers of Japan, The Japan Society of Applied Physics, Cryogenics and Superconductivity of Japan, and Institute of Physics (UK).
