The accelerated positive ions are deflected by a MAGNETIC FIELD placed at right angles to their path. The amount of deflection is proportional to the charge/mass ratio. Ions with a smaller mass are deflected more than heavier atoms. Ions with higher charges are deflected more as they interact more efficiently with the magnetic field.
