the same time in both conductors, it is considered as
originating in conductor 1, its effect on conductor 2 will be
explained. With increasing current, the flux field expands
outward from conductor 1, cutting across a portion of conductor
2. This results in an induced emf in conductor 2, as shown by
the dashed arrows in figure 12.
