    AC energy is coupled inductively in the same way a transformer works.
    There is a coil in the device to be charged that receives the AC signal from the charger.

    Magnetic coupling...... The charger is in effect a two-piece "transformer" which only transfers power when the item is installed on its charger...

    It is called electromagnetic induction.
