Two particles are ejected horizontally into a region of vertical magnetic field, and are deflected in opposite directions in the horizontal plane. The particle deflected to the right has positive charge; the one deflected to the left has negative charge.

Question

Quizplus · Accepted Answer

The direction of deflection in a magnetic field depends on the charge of the particle. According to the right-hand rule, a positively charged particle moving into a magnetic field and deflected to the right indicates the magnetic field is directed out of the page, while a negatively charged particle deflected to the left confirms this orientation, as the force direction is opposite for negative charges.
