Two long, straight wires are parallel and are separated by a distance of d = 0.250 m.?
The top wire in the sketch carries current I1 = 4.50 A, toward the right, and the bottom wire carries current I2 = 5.60 A, also to the right. At point P, midway between the two wires, what are the magnitude and direction of the net magnetic field produced by the two wires?

r = d/2
Btop = μo i1 / (2 π r)
Bbot = μo i2 / (2 π r)
B = Bto - Bbot
B = μo (i1 - i2) / (2 π r) = 1.76x10^-6 T
B is perpendicular to the plane containing the wires and is directed inside that plane
