Consider the portion of a circuit in Figure 18.75. The wire rests on top of the two compasses. When no current is running,

both compasses point north (direction shown by the gray arrows). When current runs in the circuit, the needle of compass 1

deflects as shown. In what direction will the needle of compass 2 point? Draw a sketch indicating its deflection.
