Physics - Electromagnetic Induction

Practise 33 KCET previous year questions on Electromagnetic Induction, compiled from papers spanning 2007 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 KCET tests.

Electromagnetic Induction has been asked in 19 of the 20 years of KCET papers analysed (2007–2026), with 33 questions in all. 39% of them were easy, 48% moderate and 12% tough. Most of its questions came from 2024, with 4 questions that year. In the last three years (2024–2026) it had 7 questions across 3 papers, about 2.3 per paper.

The chapter's 6 topics are not weighted equally: Magnetic Flux, Faraday's and Lenz law (15 questions, 45%), Self and Mutual Inductance (7 questions, 21%), and Motional and Rotational EMF (6 questions, 18%) have been asked the most. Magnetic Flux, Faraday's and Lenz law has also led over the last five years, with 7 questions. Motional and Rotational EMF has produced the most tough questions (3).
