Physics - Electromagnetic Induction

Practise 25 VITEEE previous year questions on Electromagnetic Induction, compiled from papers spanning 2007 to 2022. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty VITEEE tests.

Electromagnetic Induction has been asked in 12 of the 18 years of VITEEE papers analysed (2006–2024), with 25 questions in all. 52% of them were easy, 24% moderate and 24% tough. Most of its questions came from 2016, with 5 questions that year. In the last three years (2022–2024) it had 4 questions across 1 paper, about 4 per paper.

The chapter's 6 topics are not weighted equally: Magnetic Flux, Faraday's and Lenz law (10 questions, 40%), Self and Mutual Inductance (7 questions, 28%), and Inductance (3 questions, 12%) have been asked the most. Over the last five years the most frequent topics have been Self and Mutual Inductance (2), LR Circuit (1), and Magnetic Flux, Faraday's and Lenz law (1). Self and Mutual Inductance has produced the most tough questions (3).
