A Van de Graaff generator accumulates charge. This can be explained using an understanding of electrostatic charge. Electrostatic charge can be produced and detected using insulators such as polythene and Perspex. 
Friction causes electrons to be transferred from the cloth to the polythene rod. 
 
Charged objects are surrounded by an electric field. Other charged objects in the electric field experience an attractive or repulsive force. 
 
Charging by induction occurs when a charged object is brought close to a neutrally charged object.
