The Correct Option is C
Solution and Explanation
Application of Right-Hand Thumb Rule:
- The magnetic field due to a current-carrying wire follows the right-hand thumb rule:
- Point the thumb in the direction of current (east to west).
- The curled fingers indicate the direction of the magnetic field around the wire.
- At a point above the wire, the magnetic field is directed towards the north.
Thus, the correct answer is North.
