This mathematical preparation enables the student to appreciate the continuity and differentiability requirements of electromagnetic fields.
The authors begin with the empirical laws of Coulomb, Gauss, Ampere, and Faraday, systematically building the Maxwell equations. However, the distinctive feature of Reitz & Milford is their early introduction of . While most textbooks treat relativity as an afterthought, Reitz and Milford integrate it from the start, showing how magnetic fields are simply electric fields viewed from a different inertial frame. systematically building the Maxwell equations. However
