How the NCERT Exemplar Class 12 Physics Chapter 4 Helps You
This page adds the practice layer a raw Exemplar PDF lacks. Here is what students get:
- 2026-27 Mapped Problems: Every question in the 30-problem set links to a current syllabus topic. Skip nothing by accident.
- Five Question Types in One Place: MCQ-I, MCQ-II, VSA, SA, and LA problems all in the same PDF. Pace your sitting against the real load.
- Self-Test Format: Attempt cold, mark weak problems, then return to them in revision week.
- JEE and NEET Crossover: Recent entrance papers reused Exemplar Chapter 4 setups almost verbatim. This is the cheapest way to lift your Physics score.

What's Inside the Moving Charges and Magnetism Exemplar
The Exemplar runs 6 pages. The table below shows where each sub-topic clusters so students can target weak areas fast.
| Sub-Topic Concentration | Problem Numbers |
|---|---|
| Biot-Savart law and field due to current loops | 4.1, 4.2, 4.13, 4.16, 4.22, 4.27 |
| Ampere's circuital law and solenoid field | 4.3, 4.4, 4.14, 4.23 |
| Force on a moving charge and Lorentz force | 4.5, 4.10, 4.15, 4.18, 4.28 |
| Cyclotron motion and helical paths | 4.6, 4.11, 4.24, 4.29 |
| Torque and magnetic dipole moment | 4.7, 4.8, 4.17, 4.25, 4.30 |
Moving Charges and Magnetism NCERT Exemplar Question-Type Breakdown
Five question types make up all 30 problems. Know the split before you sit down to attempt.
| Question Type | Number of Problems | Indicative Marks Each |
|---|---|---|
| MCQ-I (single correct) | 6 | 1 |
| MCQ-II (one or more correct) | 5 | 2 |
| Very Short Answer (VSA) | 5 | 1 to 2 |
| Short Answer (SA) | 6 | 3 |
| Long Answer (LA) | 8 | 5 |
| Total | 30 | - |
MCQ-II is the most-failed type. Treat each option independently - more than one can be correct.
Why the NCERT Exemplar Matters for Moving Charges and Magnetism
Three reasons to use this Exemplar alongside the NCERT textbook:
- Author overlap: The committees that write the NCERT textbook and the Exemplar overlap. Practising the Exemplar trains students for the exact phrasing CBSE markers expect.
- Entrance crossover: JEE Main 2024 reused Exemplar 4.27 on a square current loop field. NEET 2025 mirrored Exemplar 4.18 on a charged particle in crossed fields.
- Free and offline: The PDF works on a phone with no reader app. Print only the LA pages if you need to. No private question bank required.
How to Use the Exemplar PDF Alongside the NCERT Textbook in Moving Charges and Magnetism
The Exemplar is the next layer on top of the NCERT chapter. Follow these three steps:
- Finish the NCERT chapter first: Read sections, work every in-text example, attempt all back-exercises. Do not open the Exemplar until this is done.
- Attempt MCQ and VSA in one sitting: Use only your formula sheet. Time-box to 60 to 75 minutes. Mark every wrong attempt with a star.
- Tackle SA and LA over four to five short sittings: Each LA problem takes 20 to 25 minutes and trains the 5-mark answer-writing flow CBSE markers reward. Return to starred problems in the revision week before boards.
Moving Charges and Magnetism Top Formulae to Memorise Before the Exemplar
Most Exemplar problems use one of four core formulas. Lock these in before you start.
| Concept | Formula |
|---|---|
| Biot-Savart law | dB = mu0 / 4 piI dl x rhat / r squared |
| Field at centre of a circular loop | B = mu_0 I / 2 R |
| Force on a moving charge | F = q v x B |
| Torque on a current loop | tau = m x B |
