Q2 — Permanent vs induced magnets (2 marks)

State two differences between a permanent magnet and an induced magnet. (2 marks)

Mark scheme (1 mark each, max 2):

• A permanent magnet produces its own magnetic field at all times; an induced magnet only becomes magnetic when placed in a magnetic field (1).
• An induced magnet loses (most of) its magnetism when removed from the field; a permanent magnet does not (1).
• The force between an induced magnet and a permanent magnet is always attractive; between two permanent magnets it can be attraction or repulsion (1).
