Basic Electromagnetic Theory
We first present the basic field equations for describing electromagnetic phenomena in an inertial frame of reference set up in vacuum. The basic physical quantities to represent electromagnetic fields in vacuum are the electric field intensity E [V/m], the magnetic-flux density B [T], and the source quantities to produce electromagnetic fields, namely, the current density J [A/m2] and the charge density ρ [C/m]. These basic electromagnetic quantities are, in general, functions of position and time, and the relations between the field quantities, E and B, and the source quantities, J and ρ are specified by the basic field equations, what is known as the Maxwell equations.
