Check the AQA specification ↗The 4 subtopics
Each one has its own page.
- Poles of a magnetWhere magnetic forces are strongest, attraction and repulsion between poles as a non-contact force felt by both magnets, permanent and induced magnets, why induced magnetism always attracts and is lost outside the field, and testing whether a steel bar is a permanent magnet.Open →
- Magnetic fields around a magnetThe magnetic field and the magnetic materials iron, steel, cobalt and nickel, why copper is not attracted, the attractive force on magnetic materials, how field strength falls with distance and is greatest at the poles, and the direction of field lines from the north pole and why they never cross.Open →
- The compass, and plotting a magnetic fieldWhat a compass contains and why it lines up with the Earth's field, plotting the field around a bar magnet, and what the pattern shows about field strength and the Earth's core.Open →
- ElectromagnetismThe magnetic field around a current-carrying wire and what decides its strength, solenoids and why their field is stronger, the field inside and around a solenoid and which end is north, electromagnets with iron cores, showing and describing the field around a straight wire, and electromagnets lifting scrap steel and working relays.Open →

Permanent magnet vs Induced magnet
Permanent magnet: one that produces its own magnetic field all the time. Induced magnet: A material that only becomes magnetic while inside a field.
Questions from this topic
Each one with the model answer underneath.
- 1
Where on a magnet are the magnetic forces strongest?
Model answer
At the poles of the magnet.
- 2
State the general rule for the force between two magnetic poles brought close together.
Model answer
Two like poles repel each other and two unlike poles attract each other.
- 3
The north pole of one bar magnet is held close to the north pole of another. Describe the force between them.
Model answer
They push apart, because two like poles repel each other.
- 4
Why is the attraction between two magnetic poles described as a non-contact force?
Model answer
Because each magnet exerts the force on the other without the two touching.
- 5
When two magnets are brought close together, does only one of them feel a force?
Model answer
No, the two magnets exert a force on each other, so both feel a force.
- 6
What is a permanent magnet?
Model answer
A magnet that produces its own magnetic field all the time.
