Outcomes

• appreciate that there is a force on a charged particle when it moves in a magnetic field as long as its motion is not parallel to the field
• recall that a force is exerted on a current-carrying wire in a magnetic field, and how this effect is applied in simple d.c.electric motors and loudspeakers
