Cross-section of two current-carrying wires perpendicular to the xy-plane.
Cross-section of two current-carrying wires perpendicular to the xy-plane.
Two long, straight wires are oriented perpendicular to the \(xy\)-plane. Wire 1 passes through the \(x\)-axis at \(x = -d\) and Wire 2 passes through the \(x\)-axis at \(x = +d\). Both wires carry equal steady currents \(I\) directed out of the page in the \(+z\)-direction. Which of the following best describes the direction of the net magnetic field \(\vec{B}\) at point \(P\) located on the \(y\)-axis at \(y = +d\)?
