Magnetism Basics
IGCSE Edexcel Physics
6.1-6.5 Magnetism
Key Concepts:
Magnets attract and repel; magnetic field lines show direction and strength.
Section A: Magnetism
1. State what happens when like poles and unlike poles are brought together.
[2]
2. Explain what magnetic field lines show.
[2]
3. Compare magnetically hard and soft materials.
[3]
4. Explain how magnetism can be induced in a material.

Mark Scheme
1.
Like poles repel; unlike poles attract [2]
2.
Direction from N to S; spacing shows field strength [2]
3.
Hard retain magnetism; soft magnetize/demagnetize easily [3]
4.
Magnetic field aligns domains so material becomes magnetized [2]
