Physics - Electromagnetic Induction

Practise 21 Manipal (MET) previous year questions on Electromagnetic Induction, compiled from papers spanning 2010 to 2023. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty Manipal (MET) tests.

Electromagnetic Induction has been asked in 11 of the 15 years of Manipal (MET) papers analysed (2010–2024), with 21 questions in all. 62% of them were easy, 29% moderate and 10% tough. Most of its questions came from 2015, with 3 questions that year. In the last three years (2022–2024) it had 1 question across 1 paper, about 1 per paper.

The chapter's 4 topics are not weighted equally: Magnetic Flux, Faraday's and Lenz law (10 questions, 48%), Self and Mutual Inductance (7 questions, 33%), and LR Circuit (2 questions, 10%) have been asked the most. Magnetic Flux, Faraday's and Lenz law has also led over the last five years, with 2 questions. LR Circuit has produced the most tough questions (1).
