Practical Physics Principles - Second Part

This comprehensive 337-page textbook provides a systematic exploration of electromagnetic theory, beginning with fundamental concepts of magnetic fields and their interactions with current-carrying conductors, including the Lorentz force, Ampere's law, and Faraday's law of electromagnetic induction. The text progresses through three main chapters that build upon each other: the first chapter (pages 1-56) establishes the foundations of magnetic phenomena through topics such as magnetic dipole moments, the Hall effect, and energy storage in magnetic systems including coils and toroids; the second chapter (pages 57-208) advances to the mathematical framework governing current flow, introducing Stokes' theorem, cyclotron motion, Lenz's law, and the continuity equation for charge conservation; and the final chapter (pages 209-362) synthesizes these principles to examine electromagnetic wave propagation, covering harmonic waves, Maxwell's equations, wave intensity, interference, diffraction, and standing waves, while providing comparative analysis between electric and magnetic fields. Throughout the book, theoretical concepts are reinforced with multiple-choice questions.
