• A new framework of electromagnetic theory is presented on the basis of conservalion principles of energy and momentum. First, Maxwell's equations and Lorentzforce law in vacuum are derived as theorems from the conservation principles. Next,new kinds of averaging procedure, transversal and longitudinal, are introduced todeal with the macroscopic media. Electromagnetic field (E, H) and flux density (7),B) are defined as the longitudinal and transversal averages of the correspondingmicroscopic field. The polarization P and magnetization M defined as P=D -e.E,M=B -p.H are given explicit expressions in terms of microscopic electromagneticstructure of the matter. Lorentz transformation of space-time and electromagneticfield can be derived entirely within the framework of electromagnetic theory.[e1ectromagneticpolarization, ll magnetization,orce, ll Lorentz4ltheory, transversal and longitudinal averages,Poynting vector, Maxwell stress, electromagnetic body ftransformatuon
