1. The magnet attracts the material (the material sticks to the magnet). 2. The material can be magnetised temporarily when brought near a strong magnet.
Also accept: If the material is attracted to the magnet, it is magnetic.; If the material can be magnetised by rubbing it with a magnet, it is magnetic.
Common mistakes: Trying to pick up the magnet with the material.

B1 · 1 mark · Gives any valid method for testing with a magnet (attraction).
B1 · 1 mark · Gives a second valid method (e.g. magnetisation by rubbing). Accept other reasonable methods.
Worked solution
Hold the material close to a magnet: if it is pulled toward the magnet, it is magnetic. Alternatively, rub the material with a magnet and see if it becomes temporarily magnetic (can pick up small iron filings).
