Electric Charges
The physical property of matter that causes it to experience a force when placed in an electromagnetic field is called electric charge. Electric charge is a characteristic that accompanies fundamental particles, wherever they exist. The process of charging a neutral body by bringing a charged body nearby it without making contact between the two bodies is known as charging by induction.
Figures given below are showing the sequential steps of charging a conductor permanently by using the process of charging by induction.
The value of charge on a body which carries 30 excess electrons is
