A long wire with a small current element of length 1 cm is placed at the origin and carries a current of 10 A along the x-axis. The magnitude of the magnetic field, due to the element, on the y-axis at a distance 0.5 m from it, would be |
$4 × 10^{-8} T$ $5 × 10^{-8} T$ $6 × 10^{-8} T$ $2 × 10^{-8} T$ |
$4 × 10^{-8} T$ |
The correct answer is Option (1) → $4 × 10^{-8} T$ |
