Question
In the statement of Fleming’s left-hand rule, what does the direction of the forefinger represent?
- Direction of the force
- Direction of the magnetic field
- Direction of the current
- Does not represent any direction
Hint:
Fleming's left-hand rule is used to find the direction of the force acting on the current carrying conductor placed in a magnetic field.
The correct answer is: Direction of the magnetic field
In Fleming’s left-hand rule, when we keep the thumb, forefinger and middle finger mutually perpendicular to each other, the thumb represents the direction of force experienced by the conductor, the forefinger represents the direction of magnetic field and the middle finger represents the direction of current flowing through the conductor.
