What examiners said
Comprehensive responses • Most candidates correctly identified a metal that is suitable for the core of an electromagnet, with the majority choosing iron. Limited responses • Some candidates confused the metal in the core with the metal used for the coil and gave an answer of copper.
— Examiner report, February/March 2026, 0625/32 Q7(b) (Cambridge)
Comprehensive responses • Few candidates correctly explained that when there was a current in the coil, the core became an induced magnet and that this caused the steel clips to also become induced magnets with the opposite pole nearest the core of the electromagnet. Limited responses • Some candidates simply repeated the question by stating that the steel clips were attracted to the electromagne...
— Examiner report, February/March 2026, 0625/32 Q7(c) (Cambridge)
There were several good points to be made about how a hydroelectric power station generates electricity and many candidates gave strong coherent accounts. However, it appeared that many candidates had a detailed knowledge of one renewable means of generating electricity and one non-renewable method. So, in this question there were references to wind generation, wave generation, tidal, geothermal a...
