Charging a body: The process in which a body gains or loses charge particles

(electrons). There are three methods of charging a body.

1 By friction: The process in which two bodies are rubbed against each other

due to which there is a transfer of electrons between two bodies and one
becomes positively charged while another becomes negatively charged.
2 By conduction: The process of charging a body by touching with a charged

body in which the same nature of charge is produced on the conductor.

Conductor Positively charged body

3 By induction: The process of charging a body without touching the charged
body.

Induced charge
Inducing charge

Electrostatic induction:

When a charged body is brought close to the conductor, the opposite charge

is developed at the near end of the conductor while a similar charge is developed
at the far end of the conductor temporarily so long as the charged body is close to
the conductor. This phenomenon is known as electrostatic induction.

Developed charge in a conductor is called induced charge and charge of the
charged body is called inducing charge.

Inducing charge and induced charge of each nature are equal in magnitude.
