Magnetism moves to year 10

We have rationalised the teaching of magnetism in the Blueprint 5-year plan. There were originally 4 key concept,  divided in two units - one Year 8 and one Year 10.  One of those was called 'non-contact forces'. Since then, we have worked out more about how we teach the two related forces gravity and magnetism, and decided we don't need that extra concept - non-contact forces - to relate them together. Now there are only 3 concepts relating to magnetism we have put them within one unit, at year 10. Students can still experience some magnetism in year 8, in the teaching of gravitational force - by comparing gravity to the more familiar magnetic force.
