3. Determining force direction: right-hand rule and Fleming's left-hand rule
4. The DC motor: structure and operating principle
5. Back-EMF in a DC motor and its significance
6. Comparing F = BIl sin θ and F = qvB sin θ: derivation link and applications
7. Practical considerations and common experimental contexts
