Fleming's left hand rule :
The forefinger, the middle finger and the thumb of the left hand are stretched in mutually perpendicular directions. If the forefinger points in the direction of the magnetic field, the middle finger in the direction of current, then the thumb points in the direction of the force on the conductor.
