Intext Examples in Class 12 Physics Chapter 6 Electromagnetic Induction
Chapter 6 has 10 intext Examples that split into three problem types: motional EMF, flux change with a stationary coil, and self or mutual inductance. Work through all three types deliberately to cover the exam range.
| 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 |
JEE Main and NEET favour inductance problems slightly more than the NCERT Example ratio. Add extra problems beyond Examples 6.7 and 6.8 if you target these exams.
Key Formulae in Electromagnetic Induction - Class 12 Physics Chapter 6
The five formulae below appear in almost every CBSE Board and JEE Main numerical on this chapter. See the dedicated Formula Sheet for dimensional checks and a decision tree on when to use each one.
| Concept | Formula | SI Unit |
|---|---|---|
| Magnetic flux | Phi = B.A = BA cos theta | weber |
| Faraday's law | epsilon = -dPhi/dt | volt |
| Motional EMF (straight rod) | epsilon = BLv | volt |
| Self inductance (solenoid) | L = mu naught N squared A / L | henry |
| Energy stored in inductor | U = half L I squared | joule |

Electromagnetic Induction PYQ Trends - CBSE, JEE Main, NEET
Three question patterns show up most often across the last five years of exams.
- 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.

How to Study Class 12 Physics Chapter 6 Electromagnetic Induction
Most students finish Chapter 6 in three sittings. Here is a practical day-by-day split.
| 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 covers self inductance, mutual inductance, energy stored, and eddy currents. Keep a buffer of one hour for the AC generator derivation. It is a recurring 5-mark Board question.
Before starting Chapter 6, revise Chapter 4 Section 4.4 on the Lorentz force and Chapter 5 Section 5.4 on the magnetic field of a long solenoid. Both results are reused inside Sections 6.6 and 6.7 without re-derivation.
