This section deals with Electromagnetism at a level slightly higher than pre-university and is tailored towards first year Physics majors. Basic theories on Electromagnetism are re-visited and enhanced. Slightly more advanced theories of Classical Electromagnetism are introduced without most of the mathematical baggage. Derivations of simple Electromagnetism configurations are included as well. This is a very simple introduction to Classical Electromagnetism.
