6.3 recall the properties of magnetically hard and soft materials
6.5 understand that magnetism is induced in some materials when they are placed in a magnetic field.
6.8 recall that an electric surrent in a conductor produces a magentic field round it.
6.9 describe the construction of electromagnets
6.10 sketch and recognise magentic field patterns for a straight wire, a flat circular coil and a solenoide when each carrying a current
