Instead, respect the authors’ work by accessing the book legally through your library, a used copy, or an official ebook. Then, study that critical page 118 thoroughly: it marks the transition from vacuum electrostatics to the real-world behavior of materials. Master that, and the rest of electromagnetism—from Maxwell’s equations to optics—will follow.

Exploring the Fundamentals of Electromagnetism and Waves: A Review of Mazzoldi Nigro Voci Fisica 2

: The electric field is a vector field surrounding charged particles, such as protons or electrons. It exerts a force on other charged particles that are placed within it.
