In this unit pupils:
- identify magnetic materials, make a magnet and test the strength of a magnet
- use the concepts of a magnetic field, a permanent magnet and an electromagnet
- investigate factors affecting the strength of an electromagnet
- explain the working of a number of devices that use magnets and electromagnets
In scientific enquiry pupils:
- use scientific knowledge and understanding to make predictions about the behaviour of magnets and magnetic material
- use preliminary work to find out whether an approach is practicable
- investigate the strength of an electromagnet, controlling relevant variables and evaluating the limitations of the data collected
This unit is expected to take approximately 7 hours.
