Mazzoldi Nigro Voci Fisica 2: A Comprehensive Textbook on Electromagnetism and Waves
If you are looking for a textbook that covers the topics of electromagnetism and waves in a clear and rigorous way, you might want to check out Mazzoldi Nigro Voci Fisica 2: Elettromagnetismo e Onde. This book is written by three Italian professors of physics, Paolo Mazzoldi, Massimo Nigro, and Cesare Voci, who have years of teaching experience in general physics courses.
The book is divided into two parts: the first one deals with the classical theory of electromagnetism, from electrostatics to electromagnetic induction, from Maxwell's equations to electromagnetic waves. The second one focuses on the physical optics, from geometric optics to interference and diffraction, from polarization to lasers and holography.
The book is designed to be adaptable to different courses and levels of study. Each chapter starts with a description of experiments that motivate the theoretical development, and then introduces the mathematical formalism gradually and systematically. The book also contains numerous examples, exercises, problems, and self-assessment tests to help students consolidate their learning.
One of the features of this book is that it includes a PDF version with 259 pages of additional material, such as appendices, solutions to selected exercises and problems, and supplementary topics. The PDF version can be downloaded for free from the publisher's website.

In this article, we will give you a brief overview of some of the main topics covered in Mazzoldi Nigro Voci Fisica 2: Elettromagnetismo e Onde. We will also highlight some of the key concepts and formulas that you should know.
Electrostatics is the study of electric charges at rest and the forces and fields they produce. Some of the basic concepts in electrostatics are:
Electric charge: a property of matter that causes it to experience a force when placed in an electric field. Electric charge can be positive or negative, and it is conserved in any physical process.
Coulomb's law: a law that describes the force between two point charges. The force is proportional to the product of the charges and inversely proportional to the square of the distance between them. The force is also directed along the line joining the charges.
Electric field: a vector field that represents the force per unit charge exerted by an electric charge or a distribution of charges. The electric field can be calculated by using Coulomb's law or by applying the superposition principle.
Electric potential: a scalar function that represents the work done by an external agent to move a unit positive charge from a reference point to a given point in an electric field. The electric potential can be calculated by integrating the electric field along a path or by using the principle of conservation of energy.
Gauss's law: a law that relates the electric flux through a closed surface to the net charge enclosed by the surface. Gauss's law can be used to calculate the electric field or the electric potential for symmetric charge distributions.
Electromagnetism is the study of electric currents and magnetic fields and their interactions. Some of the basic concepts in electromagnetism are:
Electric current: a flow of electric charge through a conductor or a circuit. Electric current can be measured by its intensity (the amount of charge passing through a cross section per unit time) or by its direction (the direction of flow of positive charge).
Ohm's law: a law that states that the electric current through a conductor is proportional to the potential difference across it. The constant of proportionality is called the resistance and depends on the material and geometry of the conductor.
Kirchhoff's laws: two laws that describe how electric currents and potentials are distributed in a network of conductors. The first law states that the sum of currents entering a node is equal to the sum of currents leaving it. The second law states that the sum of potential differences around any closed loop is zero.
Magnetic field: a vector field that represents the force per unit charge exerted by a moving electric charge or a current on another moving charge or current. The magnetic field can be calculated by using Biot-Savart's law or by applying the superposition principle.
Ampere's law: a law that relates the magnetic flux through a closed loop to the net current passing through it. Ampere's law can be used to calculate the magnetic field for symmetric current distributions.
Lorentz force: a force that acts on a moving charge or a current in an electric and magnetic field. The Lorentz force is equal to the sum of the electric force and the magnetic force.
Faraday's law: a law that states that an induced electromotive force (emf) is generated in a loop or a circuit when there is a change in magnetic flux through it. Faraday's law can be used to explain phenomena such as electromagnetic induction, transformers, generators, and motors.
Lenz's law: a law that states that an induced current has a direction such that it opposes the change in magnetic flux that caused it. Lenz's law can be derived from Faraday's law and the principle of conservation of energy.
Electromagnetic waves are oscillating disturbances in electric and magnetic fields that propagate through space without requiring any medium. Some of the basic concepts in electromagnetic waves are:
