Foundational Physics of Magnetic Fields and Forces

Magnetic fields are fundamental to modern technology and physics, but the concepts often seem abstract and disconnected. This course provides a clear, step-by-step written guide to mastering the physics of magnetism. By the end of this course, you will possess a strong theoretical understanding of how magnetic forces arise, how currents generate fields, and how these concepts integrate into the broader framework of electromagnetism. What you'll learn: * Understand the definition, measurement, and SI units of the magnetic field (B-field). * Apply the Lorentz force law to calculate magnetic forces on moving charges and current-carrying conductors. * Analyze the sources of magnetic fields using the Biot-Savart Law and Ampère's Law for various common geometries. * Explore the concept of magnetic flux and the principles governing torque on current loops. * Practice solving introductory problems related to magnetic field dynamics and field generation. * Grasp how the electric and magnetic fields are fundamentally linked and depend on the observer's frame of reference. This text-only course begins with essential definitions and vector mathematics, progresses through the laws governing magnetic forces and sources, and concludes with foundational concepts of the electromagnetic field. This course is designed for absolute beginners in electromagnetism, physics students starting university-level coursework, or anyone seeking a rigorous, text-based introduction to magnetic phenomena. No prior advanced physics or calculus knowledge is strictly required, but basic algebra is helpful. Start building your foundational knowledge of classical electromagnetism today.
