Two long, straight parallel wires in the plane of the page are separated by a distance \(2d\). Wire 1 carries a current \(I\) directed toward the top of the page, and Wire 2 carries an equal current \(I\) directed toward the bottom of the page. Point \(P_1\) is located halfway between the wires. Point \(P_2\) is located a distance \(d\) to the left of Wire 1, and Point \(P_3\) is located a distance \(d\) to the right of Wire 2. Which of the following correctly ranks the magnitudes of the net magnetic fields \(B_1\), \(B_2\), and \(B_3\) at points \(P_1\), \(P_2\), and \(P_3\), respectively?
