Electromagnetic Induction NCERT Section-by-Section Breakdown
The table maps every section of Chapter 6 to its approximate page range in the 2026-27 PDF. Use it as a scanning index when you open the flipbook to jump directly to the section under revision.
| Section | Title | Approx. Pages | One-Line Description |
|---|---|---|---|
| 6.1 | Introduction | 1 | Historical context, Oersted to Faraday to Henry. |
| 6.2 | The Experiments of Faraday and Henry | 2 | Three classic bar-magnet and coil demonstrations. |
| 6.3 | Magnetic Flux | 1.5 | Definition Phi = B.A, weber as the SI unit. |
| 6.4 | Faraday's Law of Induction | 3 | Induced EMF equals negative time rate of flux change. |
| 6.5 | Lenz's Law and Conservation of Energy | 3 | Sign rule for the direction of induced current. |
| 6.6 | Motional Electromotive Force | 4 | EMF in a moving rod, Lorentz force route. |

Electromagnetic Induction Intext Example Inventory for Class 12 Physics
The 10 intext Examples in Chapter 6 split into three problem flavours: motional EMF, flux change with a stationary coil, and self or mutual inductance circuits. The table tags each Example so you can practise all three patterns deliberately.
| Example | Sub-topic | What it Covers |
|---|---|---|
| Example 6.1 | Magnetic flux through a coil | Phi = BA cos theta computation |
| Example 6.2 | Induced EMF in a moving conductor | Direct application of epsilon = BLv |
| Example 6.3 | Polarity using Lenz's law | Sign convention practice |
| Example 6.4 | Rectangular loop entering a field | Piecewise flux change |
| Example 6.5 | EMF in a rotating rod | epsilon = B omega L squared by 2 |
| Example 6.6 | Charge through galvanometer when flux changes | q = N delta-Phi / R |
| Example 6.7 | Self inductance of a solenoid | L = mu naught N squared A / L |
| Example 6.8 | Mutual inductance of coaxial solenoids | M calculation, two-coil setup |
| Example 6.9 | EMF and current in AC generator coil | Sinusoidal EMF expression |
| Example 6.10 | Power and torque in AC generator | Mechanical-to-electrical energy balance |
Three Examples are pure motional EMF, five are flux change with a stationary coil, and two are inductance circuits. JEE Main and NEET reverse this ratio slightly in favour of inductance, so add extra inductor problems beyond Examples 6.7 and 6.8.
What's New in the 2026-27 Edition for Electromagnetic Induction
The current 2026-27 syllabus keeps Chapter 6 at the same eight-section structure introduced after the rationalisation cycle. The chapter sits at number 6 of 14, following Magnetism and Matter and feeding directly into Chapter 7 Alternating Current.

How to Read the Electromagnetic Induction Notes Class 12 PDF (Pass-Sequence Plan)
Open the flipbook above and run three passes through the chapter. A first-time reader should budget about 5 hours total across the three passes.
- Skim pass (45 minutes): read the section headings, the bold-print definitions, all figure captions, and the Summary box at the chapter end. Do not stop on derivations.
- Detailed pass (2.5 hours): work through 6.3 to 6.7 line by line, deriving every result on paper. Mark the minus signs in Faraday's law and Lenz's law explicitly.
- Examples and Exercise pass (1.75 hours): solve all 10 intext Examples without looking at the printed answer, then attempt Exercises 6.1 to 6.17. Cross-check answers against the NCERT key.
Multi-Day Study Plan for the Electromagnetic Induction PDF
Most CBSE and JEE aspirants finish Chapter 6 in three sittings spread across three days. The plan below tracks both reading time and problem-solving time per section.
| Day | Sections | Reading Time | Practice |
|---|---|---|---|
| Day 1 | 6.1, 6.2, 6.3, 6.4 | 90 min | Examples 6.1 to 6.3, Exercises 6.1 to 6.4 |
| Day 2 | 6.5, 6.6 | 90 min | Examples 6.4 to 6.6, Exercises 6.5 to 6.10 |
| Day 3 | 6.7, 6.8 plus Summary | 120 min | Examples 6.7 to 6.10, Exercises 6.11 to 6.17 |
Day 3 is the heaviest because Section 6.7 alone houses self inductance, mutual inductance, energy stored, and eddy currents. Keep a buffer of one hour on Day 3 for the AC generator derivation, which is a recurring 5-mark Board question.
Cross-Chapter Reading Order: Chapter 4 to Chapter 5 to Chapter 6
Electromagnetic Induction does not stand alone. Two earlier chapters supply the prerequisites you need before opening Chapter 6.
- Chapter 4 Moving Charges and Magnetism: Biot-Savart law and the magnetic field of a long solenoid feed directly into the self-inductance derivation in 6.7.
- Chapter 5 Magnetism and Matter: field-line and area-vector conventions are needed to compute the flux integral in 6.3 correctly.
- Chapter 6 Electromagnetic Induction: closes the loop, then hands off to Chapter 7 Alternating Current where every AC source is, in effect, an AC generator.

Three PYQ Trends from Electromagnetic Induction (CBSE, JEE Main, NEET)
The full year-wise PYQ map (2021-2026) sits on the Collegedunia NCERT Solutions page. The three trends below summarise where the marks come from.
- Motional EMF on rails: a rod sliding on parallel conducting rails in a uniform field. CBSE Board 2025 set this as a 3-marker.
- Lenz's law sign convention: direction of induced current when a magnet approaches or recedes from a coil. JEE Main 2025 and NEET 2024 both used this stem.
- Mutual inductance plus AC generator derivation: coaxial solenoid M derivation and the NBA-omega result, set in CBSE 2024 and 2022 as 5-mark long answers.
