Contents
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
Specification References

Main Body of Lesson
Plenary
- Use this Adding Forces sheet. Student should add forces along a line and may go onto an extension activity where they both label and add up forces for a number of situations.
Homework
- Students could research the difference between distance and displacement, speed and velocity and how the change in velocity can occur by the velocity only changing direction and not magnitude. This could lead to acceleration and circular motion.
