4.1 Simple phenomena of magnetism checklist

Core

Describe the forces between magnetic poles and between magnets and magnetic materials, including the use of the terms north pole (N pole), south pole (S pole), attraction and repulsion, magnetised and unmagnetised.
Describe induced magnetism.
State the differences between the properties of temporary magnets (made of soft iron) and the properties of permanent magnets (made of steel).
State the difference between magnetic and non-magnetic materials.
Describe a magnetic field as a region in which a magnetic pole experiences a force.
Draw the pattern and direction of magnetic field lines around a bar magnet.
State that the direction of a magnetic field at a point is the direction of the force on the N pole of a magnet at that point.
Describe the plotting of magnetic field lines with a compass or iron filings and the use of a compass to determine the direction of the magnetic field.
Describe the uses of permanent magnets and electromagnets.

Explain that magnetic forces are due to interactions between magnetic fields.
Know that the relative strength of a magnetic field is represented by the spacing of the magnetic field lines.
