Answer Posted / shamim
The tendency of AC to concentrate near the
surface of a conductor is known as skineffect.
All electric currents generate magnetic fields that in turn
can affect the current . In a direct current case
everything is constant and so nothing seems to happen. With
an alternating current, however, there is a delay in the
magnetic field's response to the change in current and
the 'old' magnetic field tends to push the current towards
the outside of the conductor.
