On the lefthand side nearest to the other wire (1) the eddy current is in the opposite direction to the main current (big pink arrow) in the wire, so it subtracts from the main current, reducing it. On the righthand side (2) the eddy current is in the same direction as the main current so it adds to it, increasing it. The net effect is to redistribute the current in the cross section of the wire into a thin strip on the side facing away from the other wire. The current distribution is shown by the red arrows and color gradient (3) on the cross section, with blue areas indicating low current and green, yellow, and red indicating higher current.
