Top 5 most-repeated RBSE Class 12 Physics PYQs — Magnetism and Matter
Real previous-year questions with the exact RBSE board years they appeared in. 5 more high-yield questions — including permanent-magnet and torque questions — are in the free PDF.
Define angle of declination (magnetic declination). In the magnetic meridian of a certain place, the horizontal component of earth's magnetic field is 0.25 gauss and the dip angle is 60°. Find the value of earth's magnetic field at this place.
⚙️ Core numericalWrite two characteristics of the material used to construct a permanent magnet. Give two examples of such materials.
📌 Frequently examinedThe magnetic moments of two bar magnets are M₁ and M₂. If the angle between them is θ, write the value of the resultant magnetic moment. Also explain why soft iron is used in making electromagnets.
⭐ High-weightageDraw the hysteresis curve (B–H curve) for a ferromagnetic substance.

How Magnetism and Matter is examined in RBSE
A quick map of the chapter before you download — so you know what the questions are testing.
If you have gone through the last decade of RBSE Class 12 Physics papers, you will notice Chapter 5 (Magnetism and Matter) is tested every year without fail. It belongs to Unit III — Magnetic Effects of Current and Magnetism and is drawn from a pool of 19 previous-year questions spanning 2013–2026, spread across MCQs, very short, short and long-answer sections. The topics rotate, but the question patterns stay remarkably steady.
Expect a quick 1-mark opener on classifying diamagnetic, paramagnetic or ferromagnetic substances, or drawing the hysteresis (B–H) curve. The 2-mark questions lean on magnetic declination numericals and the properties needed to make a permanent magnet. Being a short chapter, it does not carry a long-answer derivation every year, which makes the repeated short-answer questions especially worth mastering.
So the smart way to revise this chapter is not to read it end to end, but to practise the questions RBSE actually repeats. The five questions above — and the ten in the free sample PDF — are taken straight from real board papers and tagged with the exact years they appeared, so you can see for yourself what the full RBSE Physics chapterwise PYQ book offers before you decide to buy it.
