Electromagnetic Induction

A Physics chapter of the NEET syllabus, and how to practise it for the computer-based exam.

Weightage: what the paper actually did

Electromagnetic Induction carried 4 questions in the NEET 2026 paper. One paper is a data point, not a destiny: NTA moves weight between chapters every cycle, which is why the weightage tables deserve care. The stable facts are the paper's shape: 180 questions, 720 marks, +4 right, −1 wrong.

Sample PYQs from this chapter

Real questions NTA asked from Electromagnetic Induction, with the answer and the working. Try before you peek.

Question 1 · NEET 2026

Consider a long solenoid of length ll and radius rr. If nn is the number of turns per unit length and μ0\mu_0 is the permeability of free space, the inductance of the solenoid is :
  1. A.μ0πn2r2l\mu_0\pi n^2 r^2 l
  2. B.μ0n2r2l\mu_0 n^2 r^2 l
  3. C.(μ0/2π)n2r2l(\mu_0/2\pi) n^2 r^2 l
  4. D.2μ0πn2r2l2\mu_0\pi n^2 r^2 l
Answer and explanation

Answer: A

For a long solenoid L=μ0n2AlL = \mu_0 n^2 A l, where nn is turns per unit length and AA the cross-sectional area. Substituting A=πr2A = \pi r^2 gives L=μ0πn2r2lL = \mu_0\pi n^2 r^2 l. NCERT Class 12, Electromagnetic Induction (self-inductance).

Question 2 · NEET 2026

A rectangular wire loop of sides 8 cm and 3 cm with a small cut, is moving out of a region of uniform magnetic field of magnitude 0.3 T directed normal to the plane of the loop. The emf developed across the cut, if the velocity of the loop is 2 cm s−1^{-1}, in a direction normal to the shorter side of the loop, will be:
  1. A.4.8×10−44.8 \times 10^{-4} volt
  2. B.1.2×10−41.2 \times 10^{-4} volt
  3. C.1.3×10−41.3 \times 10^{-4} volt
  4. D.1.8×10−41.8 \times 10^{-4} volt
Answer and explanation

Answer: D

The motional emf is E=BvlE = Bvl, where ll is the side perpendicular to the velocity. Since the loop moves normal to the shorter side, the effective length is the shorter side (3 cm): E=0.3×(2×10−2)×(3×10−2)=1.8×10−4E = 0.3 \times (2\times10^{-2}) \times (3\times10^{-2}) = 1.8\times10^{-4} V. Option A wrongly uses the 8 cm side.

How to practise Electromagnetic Induction

Chapter by chapter, against real past-paper questions, on a screen: NEET is computer based from 2027. Read the chapter once, then attempt its PYQs until your accuracy stops climbing, and let the wrong answers tell you which lines to reread. If the chapter keeps refusing to stick, that has its own guide. There is also a free NEET mini mock with answers.

Questions

How many questions did Electromagnetic Induction have in NEET 2026?

Electromagnetic Induction carried 4 questions in the NEET 2026 paper. Weightage shifts between cycles, so treat it as a probability, not a promise.

Where can I practise Electromagnetic Induction PYQs for NEET?

Explore available chapter-wise NEET practice in BrainIt, free until the 2027 exam. Review explanations and track chapter accuracy to guide your revision. Sample questions from this chapter are on this page.

Is Electromagnetic Induction important for NEET 2027?

It is part of the Physics syllabus the paper draws from, and NEET 2027 is computer based, so practise it on a screen. Your own accuracy in the chapter matters more than any weightage table: a heavy chapter you already score well on needs less time than a light one you keep missing.
