2. Two circular loops \( A \) and \( B \) have their planes parallel to each other, as shown in Figure \( 10.10 .2 \) Loop \( A \) has a current moving in the counterclockwise direction, viewed from above. (a) If the current in loop \( A \) decreases with time, what is the direction of the induced current in loop \( B \) ? Will the two loops attract or repel each other? (b) If the current in loop \( A \) increases with time, what is the direction of the induced current in loop \( B \) ? Will the two loops attract or repel each other?
