1. The problem statement, all variables and given/known data In this problem, you will be asked to calculate the magnetic field due to a set of two wires with antiparallel currents as shown in the diagram . Each of the wires carries a current of magnitude . The current in wire 1 is directed out of the page and that in wire 2 is directed into the page. The distance between the wires is . The x axis is perpendicular to the line connecting the wires and is equidistant from the wires. Find the magnitude of the net magnetic field created at point L by both wires. Express your answer in terms of I,d, and appropriate constants. 2. Relevant equations Bwire = uoI/2pid 3. The attempt at a solution I got the B1L created by wire 1 by point 1 only. so I thought since they have the same current and distance, they will have the same magnitude, so I just add them. But I got it wrong. one of the hint says "find the direction of B" I am confused how to find the direction for wire 1 and 2 at point L. please someone help me.. Thank you so much..
