• I can use and recall the equations and the units for this unit as shown in the equation sheet

• I can recall that magnets attract and repel other magnets

• I can state that magnets attract magnetic substances

• I can describe the properties of magnetically hard and soft materials

• I can define the term ‘magnetic field line’

• I can recall that an object placed in a magnetic field can have an induced magnetism

• I can describe a practical investigation showing the magnetic fields between magnets

• I can describe how to use two permanent magnets to produce a uniform magnetic field pattern

• I can use the right hand rule to show the magnetic field around a current-carrying wire

• I can describe how to create electromagnets

• I can draw magnetic field patterns in current carrying materials

• I can describe the forces acting on a charged particle moving in a magnetic field

• I can explain how force is generated with a current carrying wire in a magnetic field; and how this is used in loudspeakers and d.c. electric motors

• I can plot a magnetic field

• I can describe how a current can produce a magnetic field
