≈ 15 minA magnet can pull certain materials towards it without touching them — this is the magnetic force.
- Magnetic materials (a magnet attracts them): iron, steel and nickel. A steel paperclip or a tin can will stick to a magnet.
- Non-magnetic materials (a magnet does not attract them): plastic, wood, paper, glass, and metals like copper and aluminium.

Every magnet has two ends, a north end and a south end. What do we call these two ends?
If you bring the north pole of one magnet close to the north pole of another magnet, they will...
