(i) When an object is chatged by induction, there is no physical contact between the object being charged and the object used to do the charging. In contrast, charging by contact, as the name implies, involves the direct physical contact to transfer charge from one object to the another.
(ii) When an object is charged by induction, the sign of the
charge that the object acquires is opposite to that of the object used to do the charging. Charging by contact gives the object being charged the same sign of charge as the original charged object.
