Maxwell’s Equations and Electromagnetic Waves - Physics (Undergraduate Foundation)

This course covers the four Maxwell's equations in integral form, displacement current, and electromagnetic oscillations. You will learn how Gauss's Law for electricity, Gauss's Law for magnetism, Faraday's Law, and the Ampere-Maxwell Law provide a single framework for all electromagnetic phenomena. The module explains how changing electric fields create magnetic fields and how these interactions produce self-propagating electromagnetic waves that travel at the speed of light. Understanding these equations is the foundation of modern telecommunications, radio engineering, and electronics. This knowledge allows you to understand how signals travel through space, how antennas work, and how light itself behaves as a wave. Whether you are building a simple radio circuit or designing complex wireless networks, these principles govern every device that uses electricity and magnetism to transmit information. By the end of this course, you will be able to apply the four fundamental equations to calculate electric and magnetic flux, identify the role of displacement current in capacitors, and describe the mathematical properties of electromagnetic waves. You will gain the skill to determine the speed, frequency, and wavelength of these waves in different media. You will also master the relationship between oscillating charges and the radiation they produce. This course is for undergraduate engineering and physics students who need a solid grasp of field theory. It is especially useful for those aiming for careers in electrical engineering, telecommunications, or renewable energy. Even if you are just starting your degree or transitioning from secondary school, this module provides the clarity needed to handle advanced technical concepts in electromagnetism and wave optics.
