Electromagnetic Theory for CSIR NET, IIT JAM and GATE Physics
Electromagnetic Theory is the single highest-weightage topic across all major physics competitive examinations. In CSIR NET Physical Sciences, Electromagnetism features heavily in both Part B and Part C, covering everything from Coulomb’s Law through Maxwell’s equations, radiation, and waveguides. In IIT JAM Physics, Electricity and Magnetism contributes 15-20% of total marks. For GATE Physics, this is a full section. For JEST and TIFR, advanced electrodynamics, radiation, and relativistic EM are tested at the deepest level.
Pravegaa Education’s free Electromagnetic Theory PDFs are structured in 8 logical units that take the student from Coulomb’s Law through the full Griffiths-level curriculum, including vector potential, gauge transformations, EM waves, and waveguides. Each PDF is written for exam-depth conceptual clarity, calibrated to the questions that actually appear in CSIR NET and IIT JAM papers.
