Abstract
This document offers a comprehensive introduction to electrostatic and electromagnetic phenomena. It begins with the fundamentals of static electricity, including the nature of positive and negative electric charges, charge conservation, conductors and insulators, electrostatic conduction and induction, Coulomb’s law, and the principle of superposition. The second part explores the electrostatic field, analyzing its behavior due to single charges, discrete charge distributions, and continuous charge distributions, with a focus on the concept of electric field lines. The third section deals with electrostatic potential and the associated potential energy, explaining their relationship with the electric field and introducing the special case of the electrostatic dipole. The Gauss’s theorem is then introduced, followed by practical applications involving symmetrical charge distributions such as spheres and planes. The fifth part discusses conductors in electrostatic equilibrium, highlighting their properties, electrostatic pressure, the tip effect, capacitance, and the energy stored in charged conductors. It also addresses electrostatic induction and capacitors, including configurations and energy storage. The next section covers electrokinetics, focusing on electric current, Ohm’s law (macroscopic and microscopic views), Joule’s law, electrical components, electromotive force, and Kirchhoff’s laws for analyzing electric circuits. The final part introduces magnetic forces and fields, examining the behavior of magnetic field lines and presenting key laws of magnetism such as Ampère’s law and the Biot–Savart law.
