    Al I know is in order to charge something by induction, you need two coils in close proximity. Thetype of the coils is dependant on the freqency used. If the freqency is high enough an air coil would work, but you would have to be in the radio frequency range. I would think a powdered iron core will be needed and the frequency in the
    100 khz or more. One must be carefull not to emit interfering electromagnetic fields.
    you neighbour might object.

    first thank u..
    i know that i must use two coils.....the frequency that i worked on is 800 khz...
    and i face a problem wit rectification.....there is no FWR works on this high frequency
    plzzzzz if u have a full schematic for this idea sho w me it pllzzzzz..
