Detailed Solution

Fleming’s left-hand rule is the rule which can be used to find the direction of force acting on the conductor.
A magnet exerts a mechanical force on a current-carrying conductor, which makes the conductor move. To explain this force exerted on the current-carrying wire within a magnetic field, Fleming gave a rule known as Fleming’s left-hand rule. The rule states, “If we stretch the forefinger, thumb, and middle finger perpendicularly, the forefinger shows the direction of the magnetic field, the middle finger shows the direction of the current, and the thumb shows the direction of force acting on the conductor.”
