    Hold your left hand with the thumb, first finger, and second finger at right angles to each other.

    The second finger shows the current, which is pointing out of the paper.

    The first finger shows the magnetic field, which is pointing downwards.

    The thumb shows the direction of the force, which is the direction the rod moves.

    So, the rod moves from left to right.
