Q: What does IP Physics Notes (Upper Secondary, Year 3-4): 15) Electromagnetism cover?
A: Map current-generated fields, magnetic forces, and the DC motor cycle for integration into IP problem solving.
Quick recap -- Electric currents create magnetic fields, and those fields can push on other currents or moving charges. Use the right-hand grip to sketch fields and Fleming's left hand to predict the resulting forces.
Start Here
| Read time | What to take away |
| 1 second | Current can create magnetic fields, and magnetic fields can push current. |
| 10 seconds | Use right-hand grip for fields around wires and solenoids. Use Fleming's left hand for force direction in motors and current-carrying conductors. |
| 100 seconds | Work through solenoids, relays, force direction, and the DC motor cycle to practise linking field direction, current direction, and motion in one diagram. |
Keep your practice loop tight via our IP Physics tuition hub-it links each topic here to quizzes, diagnostics, and WA-style problem sets.
