This publication develops a constant macroscopic conception of electromagnetism and discusses the relation among circuit conception and filed concept. the speculation is built in successive steps from the Lorentz strength, the necessary type of Maxwell's equations in unfastened house, and compatible macroscopic types of polarized and magnetized matter.
It covers the electromagnetism of relocating our bodies and the method of electromechanical strength conversion; introduces a power-series procedure for examining quasi-static fields and quasi-stationary structures; it emphasizes the synthesis of fields rather than the research of fields. provided in an appendix, the reader also will locate, the 4-dimensional relativistic formula of macroscopic electrodynamics.
