Open in App
Solution
The correct option is A East
Since the tangent drawn to the magnetic field line at a point gives the direction of the magnetic field at this point. Therefore, the direction of the magnetic field at the point above the current flowing power line will point to the East.
Hence, Option (b) is the right answer.
