The direction of the magnetic force on a charged particle moving in a magnetic field is given by the right-hand rule. Place your right hand with your fingers pointing in the direction of the charged particle's velocity, then curl your fingers in the direction of the magnetic field. Your thumb will now point in the direction of the magnetic force on the particle.

Since the magnetic field is oriented in a certain direction in the horizontal plane, it could be either perpendicular or parallel to the charged particle's velocity. If it is perpendicular, the magnetic force will be in either the positive or negative z-direction (up or down from the horizontal plane). If it is parallel, the magnetic force will be in either the positive or negative y-direction (perpendicular to both the magnetic field and the particle's velocity). Thus, there are two possible directions for the magnetic force on the charged particle.
