Electricity and Magnetism
This unit is really just one idea wearing five different costumes: charge moves, and the path it's given decides what happens. Give it one single loop and you get a series circuit — break the loop anywhere and everything stops. Give it branching paths and you get a parallel circuit — block one branch and the rest don't care. The same 'moving charge' idea explains why some materials let it move (conductors) and some don't (insulators), why a coil of wire with current in it can act like a magnet (electromagnet), and why rubbing a balloon on your hair leaves both of you charged (static electricity). Examiners at this level are testing whether you can explain the flow, not just label a diagram.
Overview: The Shape of This Topic
Why these five ideas sit together
Electricity and magnetism in MYP Year 1 build a single chain of reasoning: charge can move (current electricity) or sit still and build up (static electricity); that moving charge needs a path, and the shape of the path (series vs parallel) decides how the circuit behaves; whether charge can move at all depends on the material (conductor vs insulator); and moving charge in a coiled wire creates a magnetic field, linking electricity to magnetism directly through the electromagnet.
- Every exam question in this topic is really asking 'what happens to the flow of charge, and why?' — not 'what is the definition?'
- Series and parallel circuits dominate the question bank because they're the easiest place to test cause-and-effect reasoning with a real, checkable answer.
- Magnetism questions test field direction and pole behaviour; electromagnet questions test the link between current and magnetism plus real-world design factors.

Command terms this topic actually uses
| Command term | What it demands | AO | Mark-earning move |
|---|---|---|---|
| State | One short factual answer — a word, phrase or number, no justification needed. | Recall | 1 mark for the correct fact alone; adding reasoning here wastes time but doesn't lose marks. |
| Identify | Pick out the correct feature, component, or circuit from what's given. | Recall/interpretation | 1 mark for naming the right thing — must match exactly what's shown in the diagram/table given. |
| Describe | Give a detailed account — usually needs a sequence or a 'what happens' statement, not just a label. | Communication | Often 1–2 marks; a bare one-word answer to a 'describe' question typically scores 0 because it lacks detail. |
| Explain | State what happens AND give the reason/mechanism behind it — a linking word like 'because' is usually needed. | Reasoning | 2 marks: one for the effect, one for the causal reason. Missing the reason caps you at half marks. |
| Calculate | Use a formula with given numbers to reach a numerical answer, with units. | Application | Marks awarded for correct formula/substitution AND final answer with unit — a right number with no working can lose method marks. |
