Magnetism and Matter solutions
NCERT Class 12 Physics Chapter 5, Magnetism and Matter, is mostly theoretical and carries 4–6 marks in the CBSE Board exam, according to official CBSE papers updated Apr 23, 2026 . These Magnetism and Matter solutions follow the NCERT text and the CBSE marking scheme to help you score in Boards and competitive tests.
Why use Magnetism and Matter solutions
Solutions are curated by subject experts and cross-verified by reviewers from official sources such as NCERT and CBSE. Every question in the solutions is mapped with the NCERT exercise and includes labelled diagrams for derivations and explanations.
Key formulas and important points are highlighted for quick revision. Common mistakes students make are listed to help you avoid easy errors in exams.
Magnetism and Matter solutions: Exam weightage and question types
According to official CBSE analysis and past papers (2010–2024), the chapter's exam footprint is small but regular. It appears across Board, JEE, NEET and CUET with consistent question types.
| Exam / Paper | Typical weightage | Common question types |
|---|---|---|
| CBSE Board | 4–6 marks | 1 MCQ, 1–2 short answers (2M, 3M), occasional derivation |
| JEE / NEET | 2–4% | Conceptual MCQs and short problems |
| CUET | 10–12% | Theory and application-based questions |
| Total questions per paper | 4–5 | Mix of MCQ, short and long answers |
What the solutions include
- Stepwise answers crafted as per the CBSE marking scheme.
- Diagrams for all derivations such as bar magnet field (axial/equatorial) and B–H hysteresis loop.
- Key relations: B = μ0(H + M), χ = M/H and μr = 1 + χ are highlighted for quick recall.
The content also flags frequently asked points like the angle of dip (90° at magnetic poles, 0° at magnetic equator) and the Curie temperature of iron ( 1043 K ).
Coverage gaps noted
The current solutions do not include stepwise JEE-style numerical walkthroughs, interactive videos, timed practice tests, printable one-pagers, or conceptual flowcharts. These are factual gaps you should cover with additional practice and mock tests.
How to use these solutions effectively
Focus on diagrams and derivations; they appear regularly in Board and competitive papers. Memorise key formulas and the differences between diamagnetic, paramagnetic and ferromagnetic materials. Practice the common MCQs and the short 2–3 mark derivations yearly asked from this chapter.
