Beschreibung
This book explains why there are different variants of Maxwell's equations, and it describes the physical meaning of the quantities they contain. It also shows how the equations for static electric and magnetic potentials are derived from Maxwell's equations. Matter exposed to the fields is an integral part of the discussion. Multipole developments are justified and derived. Furthermore, the potential for simplifications in formulating the dynamical theory as a gauge field theory is explained. The laws of optics are derived from those of electrodynamics. Justifications are provided for quasi-stationary calculations, limits are formulated, and technical examples and counterexamples are shown.
Content

The author
Martin Poppe received his doctorate in Physics from the University of Oxford in 1981. At DESY, he developed the formal foundations of matter generation from colliding virtual photons. The results were published and cited more than eighty times in thirty years. After working at CERN and Bosch, he joined Muenster University of Applied Sciences, where he taught electrical and electronic engineering. He is (co-) author of several textbooks, including "Springer Handbook of Mechanical Engineering".

Maxwell's equations in matter” are derived from those without matter and thus proven to be non-fundamental The quantity H is shown to be the fraction of the magnetic field that can be attributed to free currents The book explains why dipole densities can be added to electric fields - in contrast to pears and apples
