Consider the portion of a circuit shown in the figure. When no current is running, both compasses point north (direction shown by the pale arrows). When current runs in the circuit, the needle of compass 1 deflects as shown. The wire is on top of the compass.



Which statements are true about the direction of the needle of compass 2? Draw a sketch indicating its deflection.
It will point upward just as much as compass 1. It will deflect less than compass 1 since the current has been used up. It will deflect the same amount as compass 1. It will not deflect at all. It will switch direction and point towards the lower left. It will switch direction and point towards the upper left. Incorrect: Your answer is incorrect.
