Contenuti
The class begins with electrostatics, focusing on electric charge, fields, potential, and their applications. It then moves to magnetostatics, covering magnetic fields, forces, the Biot-Savart and Ampere's laws, and magnetic materials. Finally, electrodynamics is explored, including electromotive force, induced electric fields, Faraday's law, Maxwell's equations, electromagnetic waves, and their properties, along with the study of electric current, DC circuits, and the behavior of electromagnetic waves.
Detailed program:
1. Electrostatics: • Electric charge, electric field, and Coulomb's law. • Gauss's law and its applications. • Electric potential, potential difference, and energy. • Conductors, dielectrics, and capacitors. 2. Magnetostatics: • Magnetic field and magnetic forces. • Biot-Savart law and Ampere's law. • Magnetic materials and their properties. 3. Electrodynamics: • Electromotive force, induced electric fields, and Faraday's law of electromagnetic induction. • Maxwell's equations and their integral and differential forms. • Electromagnetic waves and their properties. Electric Current and DC Circuits: • Electric current: Definition, Ohm's law, and resistance • DC circuits: Series and parallel circuits, Kirchhoff's laws, and circuit analysis techniques • RC circuits: Time constant, charging and discharging of capacitors
