Solution
The direction of force acting on a current-carrying conductor placed in a magnetic field is given by Flemming's left-hand rue.
Fleming’s Left-hand rule states that if the thumb, forefinger, and middle finger of the left hand are stretched into mutually perpendicular directions such that the index finger and middle finger of a stretched left hand directing the magnetic field and electric current respectively then the thumb shows the direction of motion or force acting on the conductor.
Hence, Flemming's left-hand rue helps to find the direction of force acting on a current-carrying conductor placed in a magnetic field.
