Detailed Solution

When a current-carrying conductor is placed in an external magnetic field, the conductor experiences a force, and therefore the direction of this force is given by Fleming's left-hand rule.
When a current-carrying conductor is placed in an external magnetic field, the conductor experiences a force perpendicular to the field and the current flow’s direction. Fleming’s left-hand rule is employed to search out the direction of the force acting on the current-carrying conductor placed in a magnetic field.

“Fleming’s Left Hand Rule states that if we arrange our thumb, forefinger, and middle finger of the left-hand perpendicular to every other, then the thumb points towards the direction of the force experienced by the conductor, then the forefinger points towards the direction of the magnetic field and the also the middle finger points towards the direction of the electrical current”.
