Q13. An element $\Delta l = \Delta x \hat { i }$ is placed at the origin and carries a large current $I = 10 \mathrm {~A}$. The magnetic field on the $y$ axis at a distance of 0.5 m from the elements $\Delta x$ of 1 cm length is: [Figure] (1) $4 \times 10 ^ { - 8 } \mathrm {~T}$ (2) $10 \times 10 ^ { - 8 } \mathrm {~T}$ (3) $8 \times 10 ^ { - 8 } \mathrm {~T}$ (4) $12 \times 10 ^ { - 8 } \mathrm {~T}$
