(adsbygoogle = window.adsbygoogle || []).push({}); Two long, straight wires are oriented perpendicular to the computer screen, as shown in Figure 22-43, in which L = 6.0 cm. The current in one wire is I1 = 3.7 A, pointing into the screen, and the current in the other wire is I2 = 4.0 A, pointing out of the screen. Find the magnitude and direction of the net magnetic field at point P.

ok so first off i used pythagorean theorem to find the straight line distance from point to the wire coming out of the page and used that as [tex]r_{2}[/tex]. then, i used the formual for magnetic force to find the force on point P from the two wires [tex] B = \mu_{0}I_{1}/2 \pi r_{1}[/tex] and [tex] B= \mu_{0}I_{2}/2 \pi r_{2}[/tex] and added the results. The answer i'm getting is wrong.. any suggestions?? i know the current in each of the wires are going in opposite directions so the forces repel but how does that relate to a point??
