One Wire, Lying on The $x$ -Axis, Carries a Current Of

One wire, lying on the $x$ -axis, carries a current of $8.0 \mathrm{~A}$ in the positive $x$ -direction. Another wire, lying on the $\mathrm{y}$ -axis, carries a current of $12 \mathrm{~A}$ in the positive $\mathrm{y}$ -direction. What is the magnitude of the magnetic field at ( $\mathrm{x}$ , y) $=(8.0 \mathrm{~cm}, 12.0 \mathrm{~cm})$ ?

B) $4.3 \times 10^{-5} \mathrm{~T}$
C) $1.7 \times 10^{-5} \mathrm{~T}$
D) $4.0 \times 10^{-10} \mathrm{~T}$
E) $1.3 \times 10^{-5} \mathrm{~T}$
