Advice for using the PDF:
The behavior of electromagnetic waves and fields can often be described using mathematical equations, such as:
$$∇⋅E = \fracρε_0$$
$$∇⋅B = 0$$
$$∇×E = -\frac∂B∂t$$
$$∇×B = μ_0J + μ_0ε_0\frac∂E∂t$$
These are Maxwell's equations, which form the foundation of classical electromagnetism.
Q: Is Fisica 2 harder than Fisica 1?
Yes, for most students. Electromagnetism is more abstract than mechanics. You cannot "see" an electric field. The mathematics also escalates to multivariable calculus (divergence, curl, surface integrals).
Q: Do I need to know calculus before starting?
Absolutely. Chapters 2 (Gauss’s law) and 10 (Maxwell’s equations) require fluency in partial derivatives and line/surface integrals. Review your calculus notes first.
Q: Which chapters are most important for exams?
For most Italian engineering exams: Chapters 2 (Gauss), 4 (Capacitors), 7 (Ampère), 8 (Faraday), 10 (Maxwell), and 12-13 (Waves). Page 118 (dielectrics) appears in ~30% of exam problems.
Q: Is there an English translation?
No official English translation exists. However, many concepts parallel Halliday/Resnick/Krane or Young/Freedman. Use those for additional English explanations.
If you are a university student in Italy pursuing a degree in Engineering, Physics, or Computer Science, you have undoubtedly heard of the "holy trinity" of physics textbooks. Among these, "Fisica 2: Elettromagnetismo e Onde" by Mazzoldi, Nigro, and Voci stands as a cornerstone of academic study.
Students often search for specific resources online using terms like "Mazzoldi Nigro Voci Fisica 2 Elettromagnetismo E Onde Pdf 118". But what exactly makes this textbook so essential, and what lies behind the specific reference to page 118? Edises, the publisher, sells official ebooks (PDF or
Let’s break down why this book is a must-have and how to navigate its most challenging chapters.
Chapter 1 – Coulomb’s law and the electric field
The book opens with charge conservation, quantization of charge, and Coulomb’s inverse-square law. Vector nature of the electric field is introduced immediately.
Chapter 2 – Gauss’s law
Flux, divergence theorem, and applications to symmetric charge distributions. This is where students first learn to compute fields from spheres, cylinders, and planes of charge.
Chapter 3 – Electric potential
Conservative fields, potential difference, and equipotential surfaces. The relationship between field and potential (gradient) is derived carefully.
Chapter 4 – Conductors and capacitors
Electrostatic equilibrium, shielding, capacitance, and energy stored in electric fields.
Chapter 5 – Dielectrics
Polarization, electric displacement D, permittivity, and boundary conditions.
Chapter 6 – Direct current circuits
Current density, resistance, Ohm’s law, Kirchhoff’s rules, RC circuits. This chapter bridges electrostatics to real-world circuits.
Chapter 7 – Magnetic field
Magnetic force on moving charges and wires. Biot-Savart law and Ampère’s law. Advice for using the PDF:
Chapter 8 – Magnetic induction
Faraday’s law, Lenz’s law, induced electric fields, and inductors.
Chapter 9 – Magnetic properties of matter
Magnetization, magnetic field H, diamagnetism, paramagnetism, ferromagnetism.
Chapter 10 – Maxwell’s equations in integral form
The unification: Gauss for electricity, Gauss for magnetism, Faraday’s law, and Ampère-Maxwell law. This is the theoretical peak of the first half.
Chapter 11 – AC circuits
Phasors, impedance, resonance, and power in alternating current circuits.
Page 118 (or section 118) in the second volume usually falls within Chapter 4 or 5 (depending on edition), specifically:
What you will find on or near p.118 (typical excerpt):
| Concept | Presentation style | |---------|--------------------| | Magnetic flux | Clear integral definition, followed by flux change due to time-varying B or moving loop. | | Motional EMF | Lorentz force derivation: ( \mathcalE = \oint (\mathbfv \times \mathbfB) \cdot d\mathbfl ). | | Lenz's Law | Explicit sign rule explained via energy conservation. | | Example problem | Sliding bar on conductive rails in uniform B field – fully solved step-by-step. |
