Two infinitely long straight wires lie in the xy-plane along the lines $x=\pm R$. The wire located at $x=+R$ carries a constant current $I_1$ and the wire located at $x=-R$ carries a constant current $I_2$. A circular loop of radius R is suspended with its centre at $\left(0,0,\sqrt{3}R\right)$ and in a plane parallel to the xy-plane. This loop carries a constant current ? in the clockwise direction as seen from above the loop. The current in the wire is taken to be positive if it is in the $+\hat{J}$ direction. Which of the following statements regarding the magnetic field $\vec{B}$ is (are) true?
