Description

Informationen zum Autor Anupam Garg is professor of physics and astronomy at Northwestern University. Klappentext This graduate-level physics textbook provides a comprehensive treatment of the basic principles and phenomena of classical electromagnetism. While many electromagnetism texts use the subject to teach mathematical methods of physics, here the emphasis is on the physical ideas themselves. Anupam Garg distinguishes between electromagnetism in vacuum and that in material media, stressing that the core physical questions are different for each. In vacuum, the focus is on the fundamental content of electromagnetic laws, symmetries, conservation laws, and the implications for phenomena such as radiation and light. In material media, the focus is on understanding the response of the media to imposed fields, the attendant constitutive relations, and the phenomena encountered in different types of media such as dielectrics, ferromagnets, and conductors. The text includes applications to many topical subjects, such as magnetic levitation, plasmas, laser beams, and synchrotrons Zusammenfassung A graduate-level physics textbook that provides a comprehensive treatment of the basic principles and phenomena of classical electromagnetism. It includes applications to many topical subjects, such as magnetic levitation, plasmas, laser beams, and synchrotrons. It features more than 300 problems, with solutions to many of the advanced ones.
