Right-hand thumb rule:
- Right-hand thumb rule states that if a current-carrying conductor is imagined to be held in the right hand such that the thumb points in the direction of the current, then the curled fingers indicate the direction of the magnetic field.
- If the current flows in the upward direction, then the direction of the magnetic field is clockwise, then the direction facing will be the North Pole.
- If the current flows in the downward direction the direction of the magnetic field is anticlockwise, then the direction facing will be the South Pole.
EXPLANATION:
- In the given case thumb points in the east-west direction then according to the right-hand rule, the direction of the magnetic field will be above the conductor i.e., towards the north.
- Hence option 1 is the answer.
