Wireless Charging is also known as ‘Inductive charging”. It is based on mutual induction
Here electromagnetic field is used to transfer the energy from one object to other object
Induction chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery. The two induction coils in proximity combine to form an electrical transformer.
