Summary
Magnets are objects that can attract certain materials and have two poles, North and South. Unlike poles attract each other, while like poles repel.
- Magnetic Materials — materials that can be attracted by magnets. Example: Iron and nickel are magnetic materials.
- Non-Magnetic Materials — materials that cannot be attracted by magnets. Example: Wood and plastic are non-magnetic materials.
- North Pole — one of the two ends of a magnet where the magnetic force is strongest. Example: The North Pole of a magnet will attract the South Pole of another magnet.
- South Pole — the other end of a magnet where the magnetic force is strongest. Example: The South Pole of a magnet will repel the South Pole of another magnet.
