For IIT preparation in electrostatics and electromagnetism, recommended texts include J.D. Jackson's "Classical Electrodynamics" as the standard graduate-level book, alongside Griffiths' text, which is favored at the advanced undergraduate level. Other notable mentions are Smythe's "Static and Dynamic Electricity," Schwinger's work, and Stratton's classic, though the latter is hard to find. For electrical engineering, Harrington's "Time-Harmonic Electromagnetic Fields" and Balanis' "Advanced Engineering Electromagnetics" are suggested, focusing more on wave theory. Overall, a combination of these texts is advised for a comprehensive understanding of the subject.
