Contents
Outcomes
- Pupils can build a working speaker
- Pupils can understand some uses for the motor effect
Specification References
6.12 understand that a force is exerted on a current-carrying wire in a magnetic field, and how this effect is applied in simple DC electric motors and loudspeakers
Starter
Start with some more practice of FLH rule as pupils tend to struggle with this. Have a few examples on the board ready as they come in. Vary the orientations of the different parts and possibly throw in an isometric one.
