Learning objectives
What the syllabus expects you to be able to do.
- 4.1.1Describe forces between magnetic poles and between magnets and magnetic materials, using the terms north and south pole, attraction, repulsion, magnetised and unmagnetised.
- 4.1.2Describe induced magnetism.
- 4.1.3State how temporary (soft iron) and permanent (steel) magnets differ.
- 4.1.4Distinguish magnetic from non-magnetic materials.
- 4.1.5Describe a magnetic field as a region where a magnetic pole feels a force.
- 4.1.6Draw the field lines and their direction around a bar magnet.
- 4.1.7State that the field direction at a point is the direction of the force on a north pole there.
- 4.1.8Describe plotting field lines with a compass or iron filings and finding the field direction with a compass.
- 4.1.9Describe uses of permanent magnets and electromagnets.
- 4.1.10Supplement: explain magnetic forces as interactions between magnetic fields.
- 4.1.11Supplement: know that closer field lines show a stronger field.
