What is the NCERT Exemplar Class 10 Science Book?
The NCERT Exemplar Class 10 Science is an extra problem book by NCERT, separate from your textbook. For Chapter 12, it tests how well you understand magnetic field lines, the force on a conductor, the electric motor, and induction, not just whether you can repeat a definition.
- Made by NCERT: the level matches your CBSE Class 10 syllabus 2026-27.
- Higher-order thinking: questions give a field-line pattern, a compass position, or a circuit and ask you to reason.
- Board and beyond: many CBSE board and school questions follow this style.
- Free and official: the PDF here is the real NCERT book.

What is Inside Chapter 12 of the NCERT Exemplar Class 10 Science
The Exemplar opens with MCQs, then short and long answers. Many are built around a field-line pattern, a compass needle, or a solenoid circuit, so you keep applying the right-hand thumb rule for the field around a wire and Fleming's left-hand rule for the force on a conductor. The table shows the layout.
| Section | What it tests | Sample idea from Chapter 12 |
|---|---|---|
| Multiple Choice Questions | Quick concept checks with one correct option | Choosing the incorrect statement about magnetic field lines |
| Short Answer Questions | Two to three line answers with a reason or a small diagram | Explaining why a fuse of a defined rating should not be replaced by a larger one |
| Long Answer Questions | Full answers with labelled circuit diagrams and explanations | Drawing a simple electric motor and explaining how it works |
The big ideas recur: field lines, the field due to a conductor, loop and solenoid, the right-hand thumb rule, Fleming's left-hand and right-hand rules, the motor, induction, the generator, and domestic circuits. Others bring in the compass needle, the electromagnet, AC and DC, the fuse, and earthing.
Question Types in the NCERT Exemplar Class 10 Science Chapter 12
Each format trains a different skill for the board exam 2026-27.
- Single-correct MCQs: one clean idea, such as which statement about field lines is incorrect.
- Diagram-based MCQs: you read a figure and pick the correct answer, such as on which face the N-pole of a loop lies.
- Direction-based MCQs: you decide a direction, such as where the field of a wire points.
- Reasoning MCQs: you choose a condition, such as how to convert an AC generator to DC.
- Short answer (SA): two to three lines with a reason, such as why a fuse is connected in series.
- Long answer (LA): a full labelled diagram with an explanation, such as the working of an electric motor or AC generator.
Why Solve the NCERT Exemplar for Chapter 12 Magnetic Effects of Electric Current
The textbook teaches the chapter; the Exemplar tests whether you can use it. Solving it for Magnetic Effects of Electric Current is a sure way to lift your Science score.
- You master the two hand rules. The Exemplar forces you to decide which rule applies before you answer, exactly the skill the board exam tests.
- You read field-line patterns with confidence. Concentric circles around a wire, the loop field, and the solenoid field all appear as diagrams.
- You explain the motor, generator, and induction clearly. Long answers ask you to draw a motor, an AC generator, and the induction experiment, all CBSE favourites.
- You meet real-life examples. Motors in fans and mixers, the split-ring commutator, the fuse, and earthing all appear.

How to Use the NCERT Exemplar Class 10 Science Chapter 12 PDF
Treat the Exemplar as a practice book, not a reading book. A three-step routine keeps your study focused before the board exam 2026-27.
- Step 1, learn first. Finish the chapter in your textbook and Notes page so you know the field lines, the hand rules, the motor, and induction.
- Step 2, attempt on your own. Try the MCQs first, then short, then long answers. Draw every field-line pattern and circuit by hand.
- Step 3, check and fix. Compare with the Exemplar Solutions page. Mark wrong questions and redo them next day.
Topics Covered in NCERT Exemplar Class 10 Science Chapter 12
Every question sits on a small set of core ideas. If you are clear on the points below, you can attempt the whole chapter. Use this as a revision checklist for the 2026-27 session.
| Topic | What you must know |
|---|---|
| Magnetic field and field lines | That field lines are closed curves, that they never cross, and that crowded lines mean a stronger field |
| Field due to a straight conductor | That a current-carrying straight wire is surrounded by concentric circular field lines, found using the right-hand thumb rule |
| Field due to a circular loop and solenoid | That a loop behaves like a tiny magnet and a solenoid has a uniform field inside, like a bar magnet outside |
| Right-hand thumb rule | That the thumb points along the current and the curled fingers give the direction of the magnetic field |
| Force on a current-carrying conductor | That a conductor in a magnetic field feels a force perpendicular to both the current and the field |
| Fleming's left-hand rule | That the thumb, forefinger, and middle finger give force, field, and current directions for a motor |
| Electric motor | That a motor converts electrical energy to mechanical energy, using a coil, magnet, and split-ring commutator |
| Electromagnetic induction and generator | That a changing field through a coil induces a current (Fleming's right-hand rule), the basis of the AC generator |
| Domestic circuits, fuse, and earthing | That the fuse and earthing protect appliances and people from overloading and short circuits |
Master these nine ideas and you can answer almost every Chapter 12 Exemplar question.
Student Feedback
In a Collegedunia poll of 1,180 Class 10 students, 83% said the NCERT Exemplar was the most useful book for scoring above 90 in Science. Many found this chapter cleared up confusion between the hand rules and between the motor and the generator.
