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.
4.5 Electromagnetic effects sits inside Electricity and magnetism. Build the concept first, then practise selecting a model, showing working, and checking the final result.
