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

Recall from previous lesson 'what is a magentic field?' Demo on OHP using iron filings the shape of the magneic field around:

Students to sketch shapes of magnetic fields for each.
