State the rule to determine the direction of force.

The direction of magnetic force acting on a current wire placed in a magnetic field is given by Flemings left hands rule.

According to Flemings Left-hand rule:- If we arrange our left hand's thumb, index finger and middle finger mutually perpendicular to each other. And if we put our index finger in the direction of magnetic field applied and centre finger in direction of electric current then the thumb will point in the direction of the magnetic force.
