Consider the two current-carrying wires shown in FIGURE 22-61. The current in wire 1 is 3.7 A; the current in wire 2 is adjusted to make the net magnetic field at point A equal to zero.

(a) Is the magnitude of the current in wire 2 greater than, less than, or the same as that in wire 1? Explain.

(b) Find the magnitude and direction of the current in wire 2.
