A wire placed along the north-south direction carries a current of 8 A from south to north. Find the magnetic field due to a 1 cm piece of wire at a point 200 cm north-east from the piece??

From question we have,
Now, as it is in north east direction, surely it will form 45° angle, let point whose magnetic field we need to find be p.
We know that,
Therefore, the magnetic field will be 4√2 × 10⁻⁹ T.
