This memory aid covers Memory Aid within Magnetic Fields for GCSE Physics. Revise Magnetic Fields in Magnetism for GCSE Physics with 14 exam-style questions and 12 flashcards. Use this page as part of a wider topic revision path rather than treating it as an isolated fact. It is section 9 of 13 in this topic. Use it for quick recall, then test yourself straight afterwards so the memory aid becomes usable in an answer.
🧠 Memory Aid
Poles rule: "Like poles Repel — unlike poles attract." Think of people: similar personalities (like poles) clash and push each other away; opposites attract.
Field line rules — NACC:
- North to South (direction outside)
- Arrows show N-pole movement
- Closer = stronger
- Can't cross
Electromagnet strength — CIT:
- Current (increase it)
- Iron core (add one)
- Turns (add more)
Soft iron vs steel: "Soft iron = soft memory — forgets magnetism instantly. Steel = steel trap — holds magnetism forever."
Practice questions for Magnetic Fields
What happens when two like magnetic poles (e.g. north and north) are brought close together?
State the rules for the attraction and repulsion of magnetic poles.
