# NCERT Solutions for Class 12 Physics chapter 6 Electromagnetic Induction

### Let us start reading the preparation article Regarding CBSE 12 Class

NCERT solutions for class 12 Physics chapter 6 Electromagnetic Induction: In the chapter Moving Charges and Magnetism you have studied that moving charges produces a magnetic field. Here in NCERT solutions for class 12 Physics chapter 6 Electromagnetic Induction you will study that moving magnet can induce an electric current. And the equipment like an electric generator and the transformer works on this principle. In NCERT class 12 chapter 1 you have learned about electric flux and in NCERT grade 12 chapter 6 Electromagnetic Induction you will learn about magnetic flux. And this changing magnetic flux is responsible for the induction of current in a closed loop placed in the moving magnetic field or a moving coil placed in the uniform magnetic field. These NCERT solutions for class 12 Physics chapter 6 Electromagnetic Induction are high concept based. So understanding the concept of this chapter is very important to solve the questions.

The two important laws mentioned in NCERT class 12 chapter 6 Electromagnetic Induction are Fridays law. Faraday's law gives a relation between emf induced in a coil and flux while Lenz’s law gives the polarity of induced emf.

## The main topics of  NCERT solutions for class 12 Physics chapter 6 Electromagnetic Induction

6.1 Introduction
6.2 The Experiments of Faraday and Henry
6.3 Magnetic Flux
6.5 LENZ’S Law and Conservation of Energy
6.6 Motional Electromotive Force
6.7 Energy Consideration: A Quantitative Study
6.8 Eddy Currents
6.9 Inductance
6.9.1 Mutual inductance
6.9.2 Self-inductance
6.10 AC Generator

In the first paragraph, it is mentioned about the transformer. The transformer works on the principle of mutual induction. This principle is mentioned in NCERT solutions for class 12 Physics chapter 6 Electromagnetic Induction. That when two coils are placed at a small distance, due to the change in current in a coil an emf is induced in the other coil. In the transformer, we call the first coil as the primary coil and second as the secondary coil. And the emf induced in these coils is proportional to the number of turns. Based on this we classify them as a step up and step down transformers. Try yourself to find out what are step up and step down transformers.
