This comprehensive textbook covers electricity and magnetism in great depth, with the 3rd edition offering updated descriptions of electromagnetic phenomena to help students achieve a more thorough understanding of the subject.

In the 1st edition, superconductivity was emphasized, a focus that continued in the 2nd edition, which strengthened the E-B analogy by comparing equipotential surfaces in electricity to equivector potential surfaces in magnetism. The 3rd edition introduces the concept of mean magnetic flux, which aids in determining inductance from magnetic energy. It also demonstrates how vector potential can be directly used to calculate electromotive force.

A unique phenomenon is presented when applying current to a superconducting transmission line, where the induced electric field's vector potential is perpendicular to the current. This deviation from common equations can still be explained through Maxwell's theory, leading to the correct solution.

For a more in-depth grasp of electricity and magnetism, students are encouraged to use Exercises in Electricity and Magnetism by the same author, which offers 400 practice problems. This textbook is ideal for advanced students of physics, astrophysics, or engineering, as well as a valuable reference for professional scientists.

Helps readers to check their understanding of the content in the chapter by the examples throughout the text Shows the correspondence of the electric phenomena and the magnetic phenomena (E-B) analogy Presents an introduction to superconductivity at the undergraduate student level

Autorentext

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).
