The direction of the force experienced by a moving charge in a magnetic field is given by the right-hand rule. If the fingers of the right hand point in the direction of the velocity (from bottom to top), and the thumb points in the direction of the magnetic field (into the page), then the palm of the hand points in the direction of the force acting on the charge, which in this case is to the right.
