Magnetic field
In this Class 10 Science topic from the chapter “Magnetic Effects of Electric Current,” students learn how a magnetic field is produced around a magnet and a current-carrying conductor. They interpret magnetic field lines to understand the field’s direction and relative strength, apply the right-hand thumb rule, and examine the field around a straight wire, circular coil, and solenoid. The topic also introduces how electromagnets work and connects these ideas with practical applications of electric current.

Which energy conversion is an electric generator based on?
Step1: An electric generator converts mechanical energy into electrical energy. Step2: When a conducting coil rotates in a magnetic field, an electric current is induced in it due to electromagnetic induction.
What is produced around a current-carrying conductor?
When electric current flows through a conductor, it produces a magnetic field around the conductor. Its presence can be detected by the deflection of a compass needle placed nearby.
