Learning objectives:
In this unit, learners will be introduced to the phenomenon of magnetism.
Whilst making students the lifelong learners, the CIE Assessment Objectives (AOs) are mainly kept in consideration
during the course of academic practice:
 AO1 Knowledge with understanding [MCQ-Ext-P2 & Theory Ext-P4 Structured]
Questions testing this objective will often begin with one of the following words: define, state, describe, explain (using your
knowledge and understanding) or outline.
 AO2 Handling information and problem solving [MCQ-Ext-P2 & Theory Ext-P4 Structured]
Questions testing these skills will often begin with one of the following words: predict, suggest, calculate or determine.

AO3 Experimental skills and investigations [Alternate to practical - P6]
Demonstrate knowledge of how to safely use techniques, apparatus and materials. plan experiments and investigations, make
and record observations, measurements and estimates, interpret and evaluate experimental observations and data, evaluate
methods and suggest possible improvements.
Learning Outcomes:
Students will be able to:
 Describe the forces between magnets, and between magnets and magnetic materials
 Give an account of induced magnetism
 Distinguish between magnetic and non-magnetic materials
 Describe methods of magnetisation, to include stroking with a magnet, use of d.c. in a coil and hammering in
a magnetic field
 Describe methods of demagnetisation, to include hammering, heating and use of a.c. in a coil
 Draw the pattern of magnetic field lines around a bar magnet
 Describe an experiment to identify the pattern of magnetic field lines, including the direction
 Explain that magnetic forces are due to interactions between magnetic fields
 Distinguish between the magnetic properties of soft iron and steel
 Distinguish between the design and use of permanent magnets and electromagnets
