field around one conductor is opposite in direction to the field
around the other conductor. The resulting lines of force oppose
each other in the space between the wires, thus deforming the
field around each conductor. This means that if two parallel
and adjacent conductors are carrying currents in the same
direction, the fields about the two conductors aid each other.
Conversely, if the two conductors are carrying currents in
opposite directions, the fields about the conductors repel each
other.

wire exists at all points along the wire. Figure 56 illustrates
