Detailed Solution

The above statement is True.
Fleming’s left-hand rule gives the direction of the force on a current-carrying conductor placed in an external magnetic field.
Here, Fleming’s Left Hand Rule states that “if we arrange our thumb, forefinger and middle finger of the left-hand perpendicular to each other, then the thumb points towards the direction of the force experienced by the conductor, the forefinger points towards the direction of the magnetic field and the middle finger points towards the direction of the electric current.” So, whenever a current-carrying conductor is put in an external magnetic field, it experiences a force perpendicular to both the field and the direction of the flow of current. The left-hand rule of Fleming is used to determine the direction in which the force is exerted on a current-carrying conductor in a magnetic field.
