A current element $\overrightarrow{\Delta l}=\Delta x \hat{i}$ (where $\Delta x$ = 1 cm) is placed at the origin and carries a current 10 A. The magnetic field on y-axis at a distance of 0.5 m : |
$4 \times 10^{-10} T$ $4 \times 10^{-9} T$ $4 \times 10^{-8} T$ $4 \times 10^{-7} T$ |
$4 \times 10^{-10} T$ |
The correct answer is Option (1) → $4 \times 10^{-10} T$ |
