Level 5

I can describe the field pattern around magnets and coils electromagnets.

I understand that the field is different in different places around a magnet.

I can describe how the earth’s magnetic field is used for navigation.

I know coils of wire are stronger electromagnets than single wires.

I can investigate how charging the current affects the pattern in an electromagnet.

I can describe simple uses of electromagnets.

I can describe the factors that affect the strength of an electromagnet.

Level 7

I can explain magnetism by describing the behaviour of particles.

I can compare the pattern of magnetic fields around bar magnets, the earth, electromagnetic, and electric wires
