The Class 12 Physics Chapter 4 Moving Charges and Magnetism PYQ compilation has 277 board-paper questions across 23 years (2003 to 2026), sorted by marks (1 to 5) and by year (latest first). The PDF mirrors the 2026-27 CBSE pattern so that every section of the question paper is represented.
- 1-mark MCQs: 107 questions, mostly post-2023 when CBSE switched to Section A objective format.
- 2 and 3-mark VSA/SA: 43 and 78 questions respectively, focused on Biot-Savart law applications, Ampere's circuital law numericals, Lorentz force in combined fields, and moving-coil galvanometer derivations.
- 5-mark long answers: 49 questions, almost every year features one of the chapter's flagship derivations paired with a numerical.
Every question in this Class 12 Physics Moving Charges and Magnetism PYQ compilation is sourced from CBSE board papers (Delhi, Outside Delhi, Foreign, Compartment) and cross-checked against the official mark scheme, with near-duplicate questions removed by a 0.85 similarity threshold.
What the Moving Charges and Magnetism Previous Year Questions Cover
The 277-question compilation maps every concept the NCERT chapter introduces. The PDF gives heavy coverage to Biot-Savart law applications, Ampere's circuital law numericals, Lorentz force in combined fields, and moving-coil galvanometer derivations, which dominate the 3 and 5-mark bands across the 2003 to 2026 window. The 1-mark MCQ block covers conceptual definitions, formula identification, and graph-interpretation questions added since 2023.

Year-wise Spread of Class 12 Physics Chapter 4 PYQs
The compilation pulls questions from 23 distinct CBSE board years. Post-2023 papers contribute a significant share because the MCQ-heavy format multiplied the 1-mark count.
- 2026: Latest sets across 55-1-X, 55-3-X, 55-5-X. Fresh MCQ wording for moving charges and magnetism concepts plus a 5-mark OR question.
- 2024 to 2025: The largest contribution years, with MCQ banks across 55-1, 55-2, 55-3, 55-4, 55-5 sets and Compartment papers.
- 2020 to 2023: Pandemic-period reduced-syllabus papers but still feature the chapter's flagship derivations.
- 2003 to 2019: Heritage long-answer questions that remain relevant to the current pattern.
Topic Frequency in the Moving Charges and Magnetism Board Paper Questions
The 277 questions cluster into six topic buckets. The table below ranks them by how often CBSE has set a question on that topic between 2003 and 2026.
| Rank | Topic Cluster | Frequency | Typical Marks Band |
|---|---|---|---|
| 1 | Biot-Savart law (loop, solenoid axis, toroid) | ~22 per cent | 3 and 5 mark |
| 2 | Ampere's circuital law applications | ~18 per cent | 3 and 5 mark |
| 3 | Lorentz force on a charged particle | ~16 per cent | 1, 2, 3 mark |
| 4 | Force on current-carrying conductor | ~15 per cent | 2 and 3 mark |
| 5 | Cyclotron and its frequency | ~14 per cent | 2 and 3 mark |
| 6 | Moving-coil galvanometer (sensitivity, conversion) | ~15 per cent | 3 and 5 mark |
Marks-Band Attempt Strategy for the Chapter 4 PYQs
The 277 PYQs are organised marks-ascending inside the PDF so that you can practice in the exact order the CBSE paper presents them.
- 1-mark MCQs: Spend no more than 45 seconds each. 90 seconds is the danger threshold, if you cross it, mark and move on.
- 2-mark VSA: One formula plus a one-line derivation or numerical. Aim for 3 minutes.
- 3-mark SA: Two sub-parts. Typical structure: a derivation plus a numerical, or a definition plus a sketch.
- 5-mark long answer: Two main parts ("a" and "b") with an OR alternative. Allocate 12 to 15 minutes including the figure.
Recent CBSE Trend: 2024 to 2026 Pattern Shift
Three things have changed in the last three CBSE cycles that the Class 12 Physics chapter 4 previous year questions now reflect:
- Section A (MCQ + Assertion-Reason) takes 20 per cent of the paper, up from 0 in pre-2023 patterns. The PYQ compilation has 107 such questions.
- Case-study (Section D, 4 marks) appears in select Physics papers and the chapter-wise PDF preserves any that fell on Chapter 4.
- 5-mark questions almost always come with an OR alternative. The Moving Charges and Magnetism PYQ PDF preserves both branches so you can revise both options.
Common Mistakes in the Moving Charges and Magnetism Board Questions
- Writing the Biot-Savart law as dB = (μ0/4π) I dL/r² without the sin(θ) or cross-product direction factor.
- Confusing the magnetic field at the centre of a loop (μ0I/2R) with the field on its axis at distance x.
- Forgetting that the Lorentz force does no work on a charged particle (the speed never changes, only direction).
- Using the cyclotron frequency formula without checking that the particle stays non-relativistic.
- Computing galvanometer-to-ammeter conversion using series shunt instead of parallel shunt.
Student Pulse on Moving Charges and Magnetism PYQ Practice
- 69 per cent said the Biot-Savart law applied to a circular loop was the most-tested 3-mark question between 2003 and 2026.
- 55 per cent reported gaining 4 to 6 marks after solving every cyclotron and galvanometer PYQ in this PDF.
- 42 per cent said a Lorentz-force numerical with combined electric and magnetic fields appeared in their CBSE 2026 paper.
- Average time to complete all questions: spread across 7 study sessions.
How These PYQs Pair with the Other Chapter 4 Resources
Solving previous year questions in isolation gives you only half the prep. Pair the PYQ PDF with the matching concept and formula resources for the same chapter.
- Stuck on a derivation? Open the NCERT Solutions for Chapter 4 Moving Charges and Magnetism for step-by-step worked answers to every NCERT back exercise.
- Need quick formula recall? The Moving Charges and Magnetism Formula Sheet compiles all key formulas and constants for last-day revision.
- Concept revision? The Moving Charges and Magnetism Notes page covers definitions, derivations, and diagrams.
- Extra practice? The NCERT Exemplar Solutions for Chapter 4 add deeper-level problems beyond the back exercises.
How to Use the Moving Charges and Magnetism PYQ PDF Most Effectively
The 277 questions are sequenced for a three-pass revision plan:
- Pass 1 (Day 1 to 2): Attempt every 1-mark MCQ (107 questions). Mark every wrong attempt and re-read the relevant NCERT paragraph.
- Pass 2 (Day 3 to 5): Solve all 2-mark and 3-mark VSA/SA questions (121 total). Time yourself: 3 minutes per 2-mark, 5 minutes per 3-mark.
- Pass 3 (Day 6 to 10): Tackle the 49 five-mark long answers. Each one is essentially a board-paper Section E in miniature: write the full derivation, then the numerical, then verify direction and units.

Ans. The PDF contains only the questions, sorted by marks and year, so you can attempt them as a practice paper. For step-by-step solutions, open the matching NCERT Solutions page or refer to the official CBSE mark scheme for the relevant year.
Ques. What is the magnetic field?
Ans. The magnetic field at a point is the region around a moving charge or current where another moving charge experiences a force. It is a vector quantity measured in tesla (T), where 1 tesla equals 1 newton per (ampere-metre).
Ques. How is the Biot-Savart law stated?
Ans. The Biot-Savart law states that the magnetic field dB produced at a point by a small current element I dL is proportional to I dL, the sine of the angle between dL and the position vector r, and inversely proportional to r². In vector form: dB = (μ0/4π) (I dL × r̂)/r².
Ques. What are magnetic field lines?
Ans. Magnetic field lines are imaginary directed curves drawn so that the tangent at every point gives the direction of the magnetic field at that point. They form closed loops (unlike electric field lines), emerge from the north pole and re-enter at the south pole outside a magnet, and never cross each other.
