Question

Two parallel long wires are mounted on two poles separated 100 (m) apart. Each wire (has a radius of a = 1 [inch]) carries two opposite currents of 2 [kA) as shown in the Figure.2. Determine the magnetic flux passing through the region bounded by the conductors and the two consecutive poles. Figure 2.
