These foundational topics are crucial because Maxwell's equations, the core of electromagnetism, are expressed using vector calculus. Without a solid grasp of these mathematical tools, mastering the rest of electromagnetics is exceedingly difficult.
If you need immediate, high-quality reference material for Electromagnetic Field Theory without spending money, several world-class resources are completely free and legal: 1. NPTEL / Swayam (India)

Induced Electromotive Force (EMF) and transformer/motional EMF.
Calculation for line, surface, and volume charges.
Poynting Vector and Poynting Theorem (Power flow in EM waves). Skin Depth and Wave Polarization. Reflection and Refraction of plane waves. 6. Transmission Lines and Waveguides Practical applications of EM wave guiding structures:
Historical asides punctuate the technical march—Faraday’s intuitive lines, Maxwell’s synthesis into unified field laws, Hertz’s experimental proof, and the 20th century’s engineering translation into radios, radars, and fiber optics. These vignettes tie mathematical formalism back to human curiosity and invention, reminding readers that the theory was forged to understand and build. NPTEL / Swayam (India) To give you an
