# A long, straight wire carrying a constant current \(I_1\) directed toward the top of the page lies in the same plane as a square conducting loop carrying a constant clockwise current \(I_2\). The left and right sides of the square loop are parallel to the straight wire. Which of the following correctly identifies the direction of the net magnetic force on the loop and compares the magnitudes of the magnetic forces exerted on the left side (\(F_{\text{left}}\)) and right side (\(F_{\text{right}}\)) of the loop?

A long, straight wire carrying a constant current \(I_1\) directed toward the top of the page lies in the same plane as a square conducting loop carrying a constant clockwise current \(I_2\). The left and right sides of the square loop are parallel to the straight wire. Which of the following correctly identifies the direction of the net magnetic force on the loop and compares the magnitudes of the magnetic forces exerted on the left side (\(F_{\text{left}}\)) and right side (\(F_{\text{right}}\)) of the loop?

![A thin vertical line representing a long straight wire carries an upward arrow labeled I_1 at its top end. To the right of the wire, a square loop with side length a is drawn in the same plane. The left edge of the square loop is parallel to the vertical wire at a distance d. Four arrows along the sides of the square loop indicate a clockwise current labeled I_2: an upward arrow on the left side, a rightward arrow on the top side, a downward arrow on the right side, and a leftward arrow on the bottom side. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1785831083-j00aMi.jpg)

- **A.** Direction of net force: Away from the wire ; Magnitude comparison: \(F_{\text{left}} > F_{\text{right}}\)
- **B.** Direction of net force: Toward the wire ; Magnitude comparison: \(F_{\text{left}} > F_{\text{right}}\)
- **C.** Direction of net force: Toward the wire ; Magnitude comparison: \(F_{\text{left}} = F_{\text{right}}\)
- **D.** Direction of net force: Away from the wire ; Magnitude comparison: \(F_{\text{left}} < F_{\text{right}}\)
