Electricity and Magnetism Syllabus and Reference Book for each topic (IIT-JAM Preparation)

 Concepts of Physics (part II) by H C Verma and Introduction to Electrodynamics by David J Griffith is good for topics like Coulomb’s law, Gauss’s law. Electric field and potential. Conductors, capacitors, dielectrics, dielectric polarization, volume and surface charges, electrostatic energy. Biot-Savart law, Ampere’s law, Faraday’s law of electromagnetic induction, Self and mutual inductance. It is important to read all the above from both books for a better understanding.

For Alternating currents, Simple DC and AC circuits with R, L, and C components Concepts of Physics (part II) by H C Verma or any basic electronic book  will be better.

 For Displacement current, Maxwell’s equations and plane electromagnetic waves, Poynting’s theorem, reflection and refraction at a dielectric interface, transmission and reflection coefficients (normal incidence only), Lorentz Force and motion of charged particles in electric and magnetic fields Electro-Magnetic Theory and Electro-Dynamics by Satya Prakash and Introduction to Electrodynamics by David J Griffith will be better. You may find some typo error in Satya Prakash but you can easily find that.
