Short paper: Electricity and Magnetism — W. J. Duffin (PDF)

Introduction

William J. Duffin’s "Electricity and Magnetism" is a concise textbook aimed at undergraduate physics students. It covers the classical theory of electrostatics, magnetostatics, and electrodynamics, emphasizing mathematical clarity and problem-solving. The book is valued for its clear derivations, worked examples, and exercises suited to a one-semester course.

First published in the 1970s, Duffin’s text never sought the spotlight. It doesn’t have the conversational wit of Griffiths or the historical richness of Purcell. What it does have—and what has kept it in print for over five decades—is a nearly perfect sense of pedagogical flow. electricity and magnetism w j duffin pdf

Section 3: Magnetostatics (Chapters 7-9)

• Chapter 7 – Magnetic Fields and Biot-Savart Law: The field from moving charges, the Biot-Savart Law, and the force between current-carrying wires.
• Chapter 8 – Ampere’s Law: The magnetic analog of Gauss’s Law. Duffin’s use of symmetry to solve for ( \mathbfB ) is methodical.
• Chapter 9 – Magnetic Materials: Diamagnetism, paramagnetism, ferromagnetism, and the ( \mathbfH ) field. He demystifies the ( \mathbfB ) vs. ( \mathbfH ) confusion that plagues many students.

• Biot–Savart law and Ampère’s law
• Magnetic vector potential A and gauge choices
• Magnetic materials, magnetization M, and H-field
• Forces and torques on magnetic dipoles and current distributions
