Matter & Interactions II, Weeks 13 and 14

I’m combining two weeks in this post. The first week, we dealt with magnetic forces. One thing that I have never thought much about is the fact that the quantity is effectively an electric field, but one that depends on velocity. When velocity is involved, reference frames are involved, and that of course means Einstein …

Conceptual Understanding in Introductory Physics XVIII: The Maxwell Equations

The Maxwell equations contain everything mentioned in an introductory calculus-based electromagnetic theory course, and then some. They contain detailed mathematical structure and deep insight into electromagnetic fields. They are a magnificent playground for learning the various theorems of vector calculus, and applying these theorems to the fields of particles naturally leads to things like divergence, …
