Moving Charges and Magnetism for Competitive Physics Exams

Preparing for competitive physics exams requires a deep, intuitive understanding of how electric charges behave in motion and how magnetic fields interact with matter. This text-based course breaks down complex electromagnetic concepts into clear, digestible explanations designed to help you tackle rigorous exam questions with confidence. You will learn to transition from basic definitions to solving intricate problems involving magnetic forces and materials. What you'll learn: Understand the foundational principles of magnetic fields and the Biot-Savart Law; Calculate the magnetic force on moving charges and current-carrying conductors; Apply Ampere's Law to find magnetic fields in high-symmetry configurations; Analyze the behavior of magnetic dipoles and torque in uniform magnetic fields; Classify and distinguish between diamagnetic, paramagnetic, and ferromagnetic materials; Practice solving structured, exam-style physics problems through step-by-step written derivations. The course begins with essential terminology and the historical context of magnetism, before guiding you systematically through electromagnetic induction, force equations, and the properties of magnetic substances. This program is designed for students preparing for advanced engineering and science entrance exams, with no prior knowledge of magnetism required beyond basic high school algebra and introductory electrostatics.
