What is the difference between induction and charging by conduction?
Charging by conduction requires contact between two objects.
Charge is transferred directly from one object onto the
other.
For charging by conduction
1. There is electrical contact between the two bodies.
2. The charges on the charged body are transferred to the object
being charged.
3. Therefore the charges on the charged body decreases and
increases on the body being charged.
4. The charges gained by the object being charged can never exceed
that of the charged body
Charging by induction is done without contact and solely by causing
charges to move about in one object by the electric and magnetic
fields produced in the other object.
For charging by induction
1. The charged object never touches the object being charged.
2. The charged object does not lose or gain electrons
3. The charged object just polarizes the object being charged
4. The object being charged receives charges opposite to the
polarity of the charged body.
