Physics - Electromagnetic Induction
Practise 18 WBJEE previous year questions on Electromagnetic Induction, compiled from papers spanning 2010 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 WBJEE tests.
Electromagnetic Induction has been asked in 13 of the 18 years of WBJEE papers analysed (2009–2026), with 18 questions in all. 56% of them were easy, 39% moderate and 6% tough. Most of its questions came from 2023, with 3 questions that year. In the last three years (2024–2026) it had 3 questions across 3 papers, about 1 per paper.
The chapter's 6 topics are not weighted equally: Magnetic Flux, Faraday's and Lenz law (7 questions, 39%), Motional and Rotational EMF (5 questions, 28%), and Induced Electric Field (2 questions, 11%) have been asked the most. Magnetic Flux, Faraday's and Lenz law has also led over the last five years, with 3 questions. Self and Mutual Inductance has produced the most tough questions (1).
