Class 12 Physics — Chapter 6: Electromagnetic Induction
90 practice questions · 30 Easy · 30 Medium · 30 Hard
Practise Class 12 Physics Chapter 6, "Electromagnetic Induction", with 90 NCERT-aligned multiple-choice questions. The set is split into 30 Easy, 30 Medium and 30 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams, JEE Main, JEE Advanced and NEET UG.
"Electromagnetic Induction" is one of the chapters where numerical problem-solving, derivations and conceptual application really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Electromagnetic Induction, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 12 Physics mastery score. A few sample questions are shown below; sign in free to practise all 90.
Key concepts: Electromagnetic Induction (Class 12 Physics)
This chapter covers Faraday's laws of electromagnetic induction, Lenz's law, motional EMF, eddy currents, and self- and mutual inductance.
- Magnetic flux
- Φ = B·A = BA cosθ; a change in flux through a circuit induces an emf.
- Faraday's law
- The induced emf equals the negative rate of change of magnetic flux: ε = −dΦ/dt.
- Lenz's law
- The induced current opposes the change causing it (the minus sign in Faraday's law) — a consequence of energy conservation.
- Motional EMF
- A rod of length l moving with speed v perpendicular to a field B develops emf ε = Blv.
- Inductance
- Self-inductance (L) opposes change in its own current; mutual inductance (M) links two coils; energy stored in an inductor is ½LI².

💡 Exam tips for Electromagnetic Induction
- Lenz's law (the minus sign) just states that induced effects oppose the change — always check the direction.
- Eddy currents are minimised by laminating cores to reduce energy loss as heat.
