Summary
Magnets are objects that can attract certain materials and have two poles, North and South, where their magnetic force is strongest.
- Magnetic Materials — materials that are attracted to magnets. Example: Iron and nickel are magnetic materials.
- Non-magnetic Materials — materials that cannot be attracted to magnets. Example: Plastic and wood are non-magnetic materials.
- North Pole — one end of a magnet that attracts the south pole of another magnet. Example: The north pole of a magnet will attract the south pole of another magnet.
- South Pole — one end of a magnet that attracts the north pole of another magnet. Example: The south pole of a magnet will attract the north pole of another magnet.
- Unlike Poles — poles that attract each other. Example: The north pole of one magnet attracts the south pole of another.
- Like Poles — poles that repel each other. Example: The north pole of one magnet repels the north pole of another.
