NC KS3 2007: 3.1 Energy, electricity and forces (b) forces are interactions between
objects and can affect their shape and motion (c) electric currents in circuits can
produce a variety of effects.
Prior knowledge
Unit 2: Forces appear whenever two objects interact.
Unit 2: Unbalanced forces cause the motion of a body to change.

Data handling
Interpreting measurements especially relating to the drawing of magnetic field lines
and drawing conclusions about field strength.
Contexts

drives, loudspeakers and headphones, motors and generators.
Electromagnets in recycling, scrap metal processing, buzzers.

Progression
ALL students should (levels 3–4):
 Recognise magnetism as a property and know some magnetic and non-magnetic
materials.
 Know that magnets come with two poles – north and south.
 Describe simple interactions of magnets and correctly use the terms apply, repel.
MOST students should (levels 5–6):
 Understand the difference between permanent and temporary magnets.
 Recognise the properties of a magnetic field and be able to draw basic field lines
for permanent magnets.
 Explain how an electromagnet works and how its strength is controlled.
SOME students will (levels 6–7):
 Explain the process by which a temporary magnet can be created.
 Interpret magnetic field lines including how stronger fields are shown, and
how lines do not cross.
 Make the links in behaviour between magnetic poles and electric charges.
 Explain uses of electromagnets such as sorting steel from aluminium, and
extrapolate to suggest further uses.
