Fleming's Left-hand rule
- It gives the force experienced by a charged particle moving in a magnetic field or a current-carrying wire placed in a magnetic field.
- It states that "stretch the thumb, the forefinger, and the central finger of the left hand so that they are mutually perpendicular to each other.
- If the forefinger points in the direction of the magnetic field, the central finger points in the direction of motion of charge, then the thumb points in the direction of force experienced by positively charged particles."
EXPLANATION:
According to question
- Forefinger (Index finger): In the direction north
- Middle finger: In the direction east
- The thumb is pointing out of the paper i.e., on top.
The force acting on the conductor will be out of the paper i.e., on top. Therefore option 3 is correct.
