The two wires shown in the figure carry currents of I = 5.58 A in opposite directions and are separated by a distance of d0 = 8.43 cm.
Calculate the net magnetic field at a point midway between the wires. Use the direction out of the page as the positive direction and into the page as the negative direction in your answer.
2*u0*i / 2*pi*r
The Attempt at a Solution
2(4piE-7)(5.58) / 2(pi)(.04215) = 5.286E-5 T
Hw system says it's incorrect, I don't know where to go from here :(
