For Class XII, NEET, JEE Main & JEE Advanced – Lecture Notes
By Ramesh Chandra (B.Tech, IIT Kanpur)
Electromagnetic Induction: Lecture Notes for Class XII, NEET, JEE Main & JEE Advanced is a complete, concept-oriented guide for mastering one of the most important and scoring units of Class 12 Physics. Carefully designed for board examinations as well as national competitive exams, this book builds strong fundamentals first and then develops the analytical and numerical skills required for high-level problem solving.
The text begins with the basics of magnetic field lines and magnetic flux, followed by the classic experiments of Faraday and Henry, leading to a clear understanding of Faraday’s laws of induction and Lenz’s law with energy conservation. Students then move systematically into motional EMF, learning the Lorentz force approach, moving rod problems, equivalent circuits, and power calculations, along with applications involving closed loops in uniform magnetic fields.
The coverage extends to rotational induction, including rotating bars, rotating coils in different magnetic field orientations, and the rotating disc generator, helping students connect theory with practical devices. The concept of induced electric fields and eddy currents is explained with physical interpretation and real-life applications.
A dedicated section on self inductance and inductors develops the derivation for solenoids, energy stored in magnetic fields, magnetic energy density, and RL circuits with current growth, decay, and time constants. This is followed by mutual inductance, including two-coil systems, coefficient of coupling, series and parallel combinations of inductors, and energy transfer between coils. The unit concludes with the AC generator and fundamentals of alternating current, covering construction, working principle, induced EMF equations, RMS values, frequency, and phase relations.
Every topic is presented with clear theory, step-wise derivations, formula logic, graphs, and exam-style numericals. The book includes worked examples, conceptual checkpoints, and extensive previous year questions from NEET, JEE Main, and JEE Advanced, enabling students to practice exactly what appears in real examinations.
Written by an IIT Kanpur alumnus with over 14 years of teaching experience, these lecture notes reflect proven classroom methods that simplify difficult electromagnetic concepts into intuitive and solvable ideas. The structured progression from fundamentals to advanced problems makes the book equally effective for learning, revision, and exam practice.
Key highlights include:
Complete NCERT-aligned theory for Class 12 Physics
Strong conceptual explanation with physical reasoning
