Magnetism and Matter JEE Main PYQ

Magnetism and Matter is an important and scoring chapter in Class 12 Physics for the JEE Main examination. Every year, several questions are asked from this unit focusing on magnetic fields, magnetic materials, magnetization, and motion of charged particles. Practicing magnetism and matter JEE Main PYQ helps aspirants understand the exact exam pattern, difficulty level, and frequently repeated concepts.

Overview of Magnetism and Matter

Magnetism arises due to the motion of electric charges and the intrinsic magnetic moments of elementary particles. In this chapter, students study the origin of magnetic fields, their interaction with currents, and the magnetic properties of matter. From a JEE Main perspective, this chapter mainly tests conceptual clarity and formula-based applications.

The important subtopics include magnetic field due to current, force on moving charges, magnetic dipole moment, magnetization, susceptibility, permeability, and classification of magnetic materials.

Magnetic Field Due to Current – PYQ Focus

The Biot–Savart Law and Ampere’s Circuital Law are frequently used to calculate magnetic fields due to current-carrying conductors. JEE Main PYQs often involve numerical problems where students must calculate the magnetic field at a given distance from a long straight wire or inside a solenoid.

Force on Current and Moving Charges

The Lorentz force law describes the force experienced by a moving charge in a magnetic field. Questions based on direction (using Fleming’s right-hand rule) and magnitude are commonly asked in magnetism and matter PYQ JEE Main papers.

For a current-carrying conductor placed in a magnetic field, the force depends on current, length of conductor, magnetic field strength, and angle between them.

Motion of Charged Particles in Magnetic Field

When a charged particle enters a uniform magnetic field perpendicular to its velocity, it undergoes circular motion. If the particle enters at an angle, the motion becomes helical. Many JEE Main PYQs are based on radius of circular path, time period, and pitch of the helix.

Magnetization and Magnetic Intensity

Magnetization is defined as the magnetic dipole moment per unit volume of a material. The magnetic response of a material is measured using magnetic susceptibility, which plays a crucial role in classifying materials.

JEE Main frequently asks conceptual questions on the relationship between magnetic field intensity (H), magnetization (M), and magnetic field (B).

Types of Magnetic Materials – PYQ Favourite

Hysteresis and Energy Loss

Ferromagnetic materials exhibit hysteresis, which means magnetization lags behind the applied magnetic field. JEE Main PYQs often test understanding of hysteresis curves, coercivity, and retentivity, especially in conceptual MCQs.

How to Prepare Magnetism and Matter PYQ for JEE Main

• Memorize all standard formulas and SI units
• Practice numerical problems from previous years
• Understand vector directions clearly
• Revise magnetic material properties thoroughly
• Solve mock tests after completing PYQs
