Class 12 Physics — Chapter 5: Magnetism and Matter
90 practice questions · 30 Easy · 30 Medium · 30 Hard
Practise Class 12 Physics Chapter 5, "Magnetism and Matter", with 90 NCERT-aligned multiple-choice questions. The set is split into 30 Easy, 30 Medium and 30 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams, JEE Main, JEE Advanced and NEET UG.
"Magnetism and Matter" is one of the chapters where numerical problem-solving, derivations and conceptual application really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Magnetism and Matter, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 12 Physics mastery score. A few sample questions are shown below; sign in free to practise all 90.
Key concepts: Magnetism and Matter (Class 12 Physics)
This chapter treats a bar magnet as a dipole, describes the earth's magnetism, and classifies materials as dia-, para- and ferromagnetic.
- Magnetic dipole
- A bar magnet behaves like a magnetic dipole with moment m; it experiences torque τ = m×B in a field.
- Magnetic field quantities
- Magnetic intensity H, magnetisation M and field B are related by B = μ₀(H + M); susceptibility χ = M/H.
- Earth's magnetism
- Described by three elements — declination, dip (inclination) and the horizontal component of the earth's field.
- Diamagnetic & paramagnetic
- Diamagnetic materials are weakly repelled (χ slightly negative); paramagnetic are weakly attracted (χ small positive).
- Ferromagnetic materials
- Strongly magnetised (large χ), show hysteresis, and lose ferromagnetism above the Curie temperature.
Key formulas — Magnetism and Matter
💡 Exam tips for Magnetism and Matter
- Remember the sign of χ: diamagnetic (small negative), paramagnetic (small positive), ferromagnetic (large positive).
- Above the Curie temperature, a ferromagnet becomes paramagnetic.
Sample questions
Iron, nickel, cobalt are:
Strongly magnetic; show domains.
Diamagnetic materials are:
χ < 0 (small).
Above Curie temperature, ferromagnet becomes:
Domains randomise.
