ABSTRACT
Electric charges are responsible for the generation of electromagnetic fields. This chapter discusses the actions of stationary or moving electric charges over electromagnetic fields. Actions of electric charges in applied electromagnetism are based on the macroscopic conception of the phenomenon. The chapter describes the volumetric distribution, superficial distribution, and linear distribution of electric charges. Static or moving electric charges alter the space properties that involve them, and these properties are characterized by actions produced in other static or moving charges. Electric field is an additional property acquired by a space when an electric charge is placed in its surroundings. With evolving studies of electromagnetism involving the presence of matter, that is, the use of ferromagnetic materials as magnetic field conductors, it is observed that the magnetic permeability is dependent on the flux density field.
