A straight currrent - carrying conductor is placed in a magnetic field such that its length is perpendicular to the field .Name and state the rule used to the find the direction of the force acting on the conductor .

Explanation

In this case Fleming.s left hand rule is used to find the direction of the force acting on the conductor .

Stretch the thumb , forefinger and middle finger of your left hand such that they are mutually perpendicular (figure 13.22). If the first (force) finger points in the direction of magnetif field and second (middle ) finger points in the direction of current, then thumb will point in the direction of motion or the force acting on the conductor .
