Answer:

FLEMING LEFT HAND THUMB RULE

IT STATES THAT IF WE STRETCH THE FIRST THREE FINGER OF LEFT HAND IN SUCH A WAY THAT THEY ARE MUTUALLY PERPENDICULAR TO EACH OTHER . THEN MIDDLE FINGER POINT TOWARDS THE DIRECTION OF CURRENT , FOREFINGER POINT TOWARDS DIRECTION OF EXTERNAL MAGNETIC FIELD THEN THUMB WILL PROVIDE THE DIRECTION OF FORCE ACTING ON CURRENT CARRYING CONDUCTOR
