Skin effect is caused by the back emf produced by the self induced magnetic flux in a conductor. ... For a DC current, the rate of change of flus is zero, so there is no back emf due to changes in magnetic flux. Therefore, the current is uniformly distributed throughout the cross section of the conductor.
