The electromagnet shown in the diagram provides a magnetic field which is used to
deflect the ion along the tube of the spectrometer.
Explain how a magnetic field can be used to deflect the ion into a circular path.
(QWC – Work must be clear and organised in a logical manner using
technical wording where appropriate)
the (magnetic) field acts at a right angle to the direction of motion
Or the velocity of the ion is perpendicular to the (magnetic) field
the force is perpendicular to the direction of motion.
the force acts as a centripetal force
Or this is the condition for circular motion
