ll electric currents generate magnetic fields that in turn
can affect the current (this is the principle behind
electric guitar pickups). 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. As the frequency increases, so
does the effect until at very high frequencies the entire
current flows in a very narrow skin on the conductor--hence
the name.
