Physics - Electromagnetic Induction

Practise 111 AP 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 AP EAMCET tests.

Electromagnetic Induction has been asked in 19 of the 24 years of AP EAMCET papers analysed (2001–2024), with 111 questions in all. 52% of them were easy, 33% moderate and 14% tough. Most of its questions came from 2021, with 19 questions that year. In the last three years (2022–2024) it had 30 questions across 28 papers, about 1.1 per paper.

The chapter's 6 topics are not weighted equally: Magnetic Flux, Faraday's and Lenz law (34 questions, 31%), Motional and Rotational EMF (26 questions, 23%), and Self and Mutual Inductance (25 questions, 23%) have been asked the most. Magnetic Flux, Faraday's and Lenz law has also led over the last five years, with 17 questions. Motional and Rotational EMF has produced the most tough questions (6).
