Class 12 Physics Practice Paper Chapter 6 Electromagnetic Induction [Free PDF]

Introduction

Welcome to Bhautik Study, your trusted platform for Physics learning and exam preparation. Class 12 Physics begins with Chapter 6- Electromagnetic Induction, the foundation of electrostatics. This chapter introduces electric charges, Coulomb’s law, the superposition principle, electric fields, dipoles, and Gauss’s law.

A strong understanding of this chapter is crucial for success in CBSE Board Exams, JEE Main, JEE Advanced, and NEET. To help students, we at Bhautik Study have prepared a free practice paper PDF for Chapter 6. It includes theoretical, numerical, and competitive-level multiple-choice questions to strengthen your concepts.

Electromagnetic Induction (EMI) is one of the most fascinating and fundamental chapters of Class 12 Physics. It deals with the phenomenon of generating an electromotive force (emf) when the magnetic flux linked with a circuit changes. This discovery, made by Michael Faraday in 1831, not only changed the course of physics but also laid the foundation for modern electrical engineering. Almost every electrical device that we use today, from transformers to power generators, operates on the principles of electromagnetic induction.

At its core, this chapter explains how a changing magnetic field can produce an electric current in a conductor. This concept bridges the gap between electricity and magnetism, and it is a natural extension of what students learn in the previous chapters on Moving Charges and Magnetism and Magnetism and Matter. In fact, Electromagnetic Induction can be considered the practical outcome of Maxwell’s equations, which unify the laws of electricity and magnetism.

One of the central ideas of this chapter is Faraday’s Law of Electromagnetic Induction. Faraday experimentally showed that whenever the magnetic flux linked with a closed circuit changes, an emf is induced in the circuit. The magnitude of this emf depends on the rate of change of flux, and its direction is given by Lenz’s Law, which states that the induced current always opposes the cause that produces it. This is not only a conceptual idea but also a direct consequence of the law of conservation of energy.

The chapter also introduces self-induction and mutual induction, two important concepts that explain how inductors work. Self-induction refers to the property of a coil to oppose a change in current flowing through it by inducing an emf in itself. On the other hand, mutual induction explains how two coils can interact—when current in one coil changes, it induces emf in the nearby coil. This principle is applied in transformers, which are essential in power transmission.

Another interesting topic covered in this chapter is eddy currents. These are currents induced in solid conductors when exposed to a changing magnetic field. While they can cause energy losses in some systems (like transformers), they are also put to use in practical applications like induction cooktops, magnetic braking in trains, and damping in galvanometers.

Electromagnetic Induction is not just about theoretical knowledge—it is extremely significant in real-world applications. For example:

• Power stations use the principle of electromagnetic induction to generate electricity on a massive scale.

• Transformers, which are based on mutual induction, make long-distance transmission of electricity possible by stepping up or stepping down voltage levels.

• Induction motors, used in almost every household appliance, function because of induced currents.

For students preparing for CBSE Class 12 Board Exams, this chapter carries high importance. Questions often focus on derivations (like induced emf, energy stored in an inductor, and mutual induction), numerical problems based on Faraday’s law, and conceptual questions on Lenz’s law and eddy currents. For competitive exams like JEE and NEET, this chapter is crucial as it frequently appears in both physics numericals and theory-based problems.

By practicing well-designed problems from this chapter, students not only strengthen their fundamentals but also develop problem-solving skills for higher-level physics. At Bhautik Study, our carefully prepared practice papers for Chapter 6 cover a wide range of questions—numerical, derivations, and application-based problems—ensuring that students gain confidence in this topic.
