# Physics Revision Notes for Class 12 for Chapter 6 Electromagnetic Induction

For a long time, electricity and magnetism were considered separate and unrelated phenomena. But in chapter 4, you studied about their relationship with each other. In this chapter, you will learn about the phenomenon of changing magnetic fields and its underlying principles. The induction of electricity due to varying magnetic fields is known as electromagnetic induction.

## Frequently asked Questions on CBSE Class 12 Physics Notes Chapter 6: Electromagnetic Induction

Q1

### What is ‘Electromagnetic induction’?

The induction of an electromotive force in a circuit by varying the magnetic flux linked with the circuit is called as the ‘Electromagnetic induction’.

Q2

### What are ‘Eddy currents’?

An eddy current is a current set up in a conductor in response to a changing magnetic field. They flow in closed loops in a plane perpendicular to the magnetic field.

Q3

### What is ‘Lenz’s law’?

Lenz’s law states that an induced electric current flows in a direction such that the current opposes the change that induced it.
