Question:medium
A straight wire is kept horizontally along the east-west direction. If a steady current flows in the wire from east to west, the magnetic field at a point above the wire will point towards:
A straight wire is kept horizontally along the east-west direction. If a steady current flows in the wire from east to west, the magnetic field at a point above the wire will point towards:
Show Hint

- East
- West
- North
- South
Show Solution
The Correct Option is C
Solution and Explanation
Application of Right-Hand Thumb Rule:
- The magnetic field generated by a current-carrying wire is determined by the right-hand thumb rule:
- Align the thumb with the direction of current flow (east to west).
- The direction in which the fingers curl represents the direction of the magnetic field encircling the wire.
- For a point located above the wire, the magnetic field is oriented towards the north.
Therefore, the correct response is North.
