Mastery checklist
Know what success looks like.
- 01
Define the system, then show every external interaction with a clear direction.
- 02
Apply Newton's laws or a conservation law component by component.
- 03
Test the result against units, limiting cases, and the direction of the predicted change.
Exam lens
Build, apply, check.
20 Magnetic fields sits inside A Level extension. Build the concept first, then practise selecting a model, showing working, and checking the final result.
