Fleming′s Left Hand Rule

Also known as the Motor Rule this is a way of determining the direction of a force on a current carrying conductor in a magnetic field.

The thumb, the first and the second fingers on the left hand are held so that they are at right angles to each other.

If the first finger points in the direction of the magnetic field and the second finger the direction of the current in the wire, then the thumb will point in the direction of the force on the conductor.
