Physics - Electromagnetic Induction

Practise 10 NEST (NISER) previous year questions on Electromagnetic Induction, compiled from papers spanning 2013 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty NEST (NISER) tests.

Electromagnetic Induction has been asked in 6 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 10 questions in all. 10% of them were easy, 70% moderate and 20% tough. Most of its questions came from 2019, with 3 questions that year. In the last three years (2024–2026) it had 2 questions across 4 papers, about 0.5 per paper.

The chapter's 4 topics are not weighted equally: Magnetic Flux, Faraday's and Lenz law (5 questions, 50%), Self and Mutual Inductance (3 questions, 30%), and Motional and Rotational EMF (1 question, 10%) have been asked the most. Magnetic Flux, Faraday's and Lenz law has also led over the last five years, with 2 questions. Self and Mutual Inductance has produced the most tough questions (1).

These are NEST (NISER) questions specifically for the Electromagnetic Induction chapter. Questions from other exams like JEE Main or NTA Abhyas (JEE Main) are organised separately under their respective exam sections.

3.Is Electromagnetic Induction an important chapter for NEST (NISER) Physics?

Electromagnetic Induction has appeared in 6 of the 16 years of NEST (NISER) papers covered here, with 10 questions across 8 papers - about one per paper it appears in.

4.What is the difficulty level of Electromagnetic Induction questions in NEST (NISER)?

Of the 10 questions analysed for this chapter, 10% are easy, 70% moderate and 20% tough. 2019 had the most, with 3 questions.

5.Which topics in Electromagnetic Induction should I focus on?

These topics have carried the most weightage in Electromagnetic Induction:

  • Magnetic Flux, Faraday's and Lenz law - 5 questions (50%)
  • Self and Mutual Inductance - 3 questions (30%)
  • Motional and Rotational EMF - 1 question (10%)
  • Self and Mutual Inductance has produced the most tough questions (1).
6.Is Electromagnetic Induction's weightage in NEST (NISER) going up or down?

Across all 8 papers analysed, Electromagnetic Induction has averaged about 1.3 questions per paper. In the last three years (2024–2026), that average has fallen, at about 0.5 questions per paper. Use the year-wise numbers on this page for the exact trend before you decide how much time to give it.
