# Four long, parallel wires are perpendicular to the page and situated at the corners of a square, as shown in the figure. The two wires on the left each carry a steady current \(I\) directed out of the page, and the two wires on the right each carry a steady current \(I\) directed into the page. Which of the following best describes the direction of the net magnetic field at the center of the square?

Four long, parallel wires are perpendicular to the page and situated at the corners of a square, as shown in the figure. The two wires on the left each carry a steady current \(I\) directed out of the page, and the two wires on the right each carry a steady current \(I\) directed into the page. Which of the following best describes the direction of the net magnetic field at the center of the square?

![A square is shown in the plane of the page with dashed lines connecting its four corners. At each of the four corners is a small circle representing a wire perpendicular to the page. The top-left corner circle and the bottom-left corner circle each contain a central solid dot, indicating current directed out of the page, and are each labeled \(I\). The top-right corner circle and the bottom-right corner circle each contain a centered cross \(\times\), indicating current directed into the page, and are each labeled \(I\). Two dashed diagonal line segments connect opposite corners, intersecting at a central point labeled \(C\). No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787461140-q24koz.jpg)

- **A.** Toward the bottom of the page
- **B.** Toward the top of the page
- **C.** Toward the right of the page
- **D.** The net magnetic field at the center is zero
