Dive into the world of electromagnetics with a focus on Maxwell's Equations, static, quasi-static, and time-harmonic phenomena. Understand key concepts like Gauss, Coulomb, and more through demonstrations and discussions. Join us on the battle plan to decode discrete charges and continuous charge distributions.
