Two long parallel wires lie in the x$-$y plane, and each carry $5\mathrm{.}0$Acurrents in opposite directions. Wire $1$ lies along the y$=3\mathrm{.}0$cm line and carries a current in the negative x direction; wire $2$ lies along the y$=0=0$ line and carries a current in the positive x direction. What is the direction of the magnetic field at the point $(0$cm$,0$cm$,1\mathrm{.}5$cm$)?$
