Two long parallel wires lie in the xy-plane, each carrying a 5.0 A current in opposite directions. Wire 1 lies along the y=3.0\mathrm{cm} line and carries a current in the positive x-direction; wire 2 lies along the y=0 line and carries a current in the negative x
-direction. What is the magnitude of the magnetic field at the point \left(0\text{}\text{cm,}\text{}1\text{}\text{.5}\text{}\text{cm,}\text{}0\text{}\mathrm{cm}\right)
?
