coil placed closely together, usually only separated by the outer casing of the two devices (< 7 mm).
Inductive wireless
charging requires a magnetic
coil be present in the phone and the wireless charger for the
charging process to work.
Wireless chargers (also known as «
inductive charging») 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 electric current to
charge the battery.

coil in a
charging pad transmitting energy via a magnetic field to a receiving
coil in the device.
