d₁ P do FIG. 1. Two very long straight wires (in cross section) that each carry a current of 4.00 A directly out of the page. The above figure shows two very long straight wires (in cross section) that each carry a current of 4.00 A directly out of the page. Distance d₁ = 6.00 m and distance d₂ 4.00 m. What is the magnitude of the net magnetic field at point P, which lies on a perpendicular bisector to the wires? * assume μ0 = 4 × 10-7 T A . m
