Answer Posted / nvnkmr
alternating current produces alternating magnetic flux inside and around the conductor. this flux produces counter emf to oppose the change in current. this effect is more at the center of conductor. so electrons tend to flow through surface. In DC there will not be any alternating magnetic field and so no Skin effect is not observed.
