A student is given an unmagnetised steel bar, an unmagnetised iron bar and a strong bar magnet.
The student is also given a box of small steel paper clips and a plotting compass.
Explain how the student could use this equipment to show that steel becomes a permanent magnet but iron becomes only an induced (temporary) magnet.
