A long straight wire along the z-axis carries a current i in the negative z-direction. The magnetic field B at a point having coordinate (x, y) on the z = 0 plane is:

Option: 1

\mathrm{\frac{\mu_0 l(y \hat{i}+x \hat{j})}{2 \pi\left(x^2+y^2\right)}}


Option: 2

\mathrm{\frac{\mu_0 I(x \hat{i}+y \hat{j})}{2 \pi\left(x^2+y^2\right)}}


Option: 3

\mathrm{\frac{\mu_0 l(x \hat{j}-y \hat{i})}{2 \pi\left(x^2+y^2\right)} }


Option: 4

\mathrm{\frac{\mu_0 l(x \hat{i}-y \hat{j})}{2 \pi\left(x^2+y^2\right)}}
