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 current 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 solenoid when each carrying a current
Starter
Recall from previous lesson 'what is a magentic field?' Demo on OHP using iron filings the shape of the magneic field around:
- a straight wire
- a flat coil
- a solenoid
Students to sketch shapes of magnetic fields for each.
