Physics - Electromagnetic Induction

Practise 151 JEE Main previous year questions on Electromagnetic Induction, compiled from papers spanning 2002 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty JEE Main tests.

Electromagnetic Induction has been asked in 24 of the 25 years of JEE Main papers analysed (2002–2026), with 151 questions in all. 30% of them were easy, 44% moderate and 25% tough. Most of its questions came from 2023, with 24 questions that year. In the last three years (2024–2026) it had 35 questions across 49 papers, about 0.7 per paper.

The chapter's 6 topics are not weighted equally: Magnetic Flux, Faraday's and Lenz law (45 questions, 30%), Motional and Rotational EMF (34 questions, 23%), and Self and Mutual Inductance (29 questions, 19%) have been asked the most. Over the last five years the most frequent topics have been Motional and Rotational EMF (24), Magnetic Flux, Faraday's and Lenz law (19), and Self and Mutual Inductance (16). Magnetic Flux, Faraday's and Lenz law has produced the most tough questions (13).
