Magnetic Fields Due to Currents

A single current$-$carrying circular loop of radius $\backslash ($ R $\backslash )$ is placed next to a long, straight wire, as shown in the figure. The current in the straight wire points to the right and is of magnitude $\backslash ($ I$=1\mathrm{.}0\backslash$mathrm$\{$~A$\}\backslash ).$ The magnetic field at the center of the loop is zero. What is the magnitude and direction $($circle one$)$ of the current in the loop? Show your work.
