The cross sections of two parallel wires are shown in Figure 29.27 located d = 7.8 cm apart in air. The left wire carries a
current of 7.5 A into the paper, and the right wire carries a current of 3.4 A out of the paper. What is the resultant
magnetic induction at the midpoint A due to both wires? (Hint: Superimpose the fields due to each wire to find the
resultant field.)
