## Content

• Electromagnetic field equations: Maxwell equations in space and time domain, both in differential and integral form. Emphasis is laid to dynamic phenomena, which the third and fourth Maxwell equations explain and describe(electromagnetic induction, displacement current etc). Scalar and vector potentials are defined. Coulomb and Lorenz gauges are analyzed. The energy of electric charge and current distributions, the electromagnetic field energy and Poynting vector are analyzed. The equation of electromagnetic field energy conservation is proved.

• Solution of Maxwell's equation in Space and time domain-electromagnetic wave propagation: a) plane electromagnetic waves b) electromagnetic properties of materials c) propagation of electromagnetic waves in space and material media d) boundary conditions e)electromagnetic field of time varying charges and currents.

• Electromagnetic field of moving charges: Global solution of Maxwell equations concerning retarded potentials. Solution is found for the electromagnetic field of moving particles with constant velocity or accelerated. Emphasis is laid to the limited velocity of electromagnetic force propagation.

• Relativistic electrodynamics: Postulate of electric charge conservation, Lorenz transformations and unchanging of Maxwell' equations and their solutions. Transformations of scalar and vector potentials, electric and magnetic field intensities. Emphasis is laid to the unified entity of the electromagnetic force
