What You’ll Learn in Chapter 4 – Moving Charges and Magnetism

This chapter is an extension of electric current concepts and explains how a moving electric charge creates a magnetic field. It also covers how this magnetic field influences other moving charges or current-carrying conductors. You’ll study both theoretical and numerical aspects of magnetism related to electric current.

Key topics covered in this chapter include:

• Magnetic force on a moving charge

• Motion of a charged particle in a magnetic field

• Biot-Savart law

• Magnetic field due to a current-carrying wire, loop, and solenoid

• Ampere’s Circuital Law

• Force between two parallel current-carrying conductors

• Torque on a current loop

• Galvanometer, ammeter, and voltmeter

Each of these topics is linked with real-world applications, such as motors, measuring instruments, and magnetic field detection tools. That’s why solving each question in your NCERT textbook is essential.
