Physics - Electromagnetic Induction

Practise 67 TS EAMCET previous year questions on Electromagnetic Induction, compiled from papers spanning 2001 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty TS EAMCET tests.

Electromagnetic Induction has been asked in 19 of the 24 years of TS EAMCET papers analysed (2001–2024), with 67 questions in all. 39% of them were easy, 46% moderate and 15% tough. Most of its questions came from 2021, with 7 questions that year. In the last three years (2022–2024) it had 17 questions across 17 papers, about 1 per paper.

The chapter's 6 topics are not weighted equally: Motional and Rotational EMF (22 questions, 33%), Self and Mutual Inductance (18 questions, 27%), and Magnetic Flux, Faraday's and Lenz law (18 questions, 27%) have been asked the most. Over the last five years the most frequent topics have been Magnetic Flux, Faraday's and Lenz law (11), Motional and Rotational EMF (9), and Self and Mutual Inductance (7). Motional and Rotational EMF has produced the most tough questions (4).
