- Magnetism and Electromagnet-ism
- Magnetism describes the ability of magnets to attract and repel other magnets without touching them.
- A magnets poles are where the magnetic forces are the strongest
- Induced magnets are magnetic materials that become a magnet when in a magnetic field. When they are moved away from the permanent magnet the magnetic material will stop being a magnet. This is called induced magnetism.
- Opposite poles attract and like poles repel. This is an example of a nan-contact force
- Iron, Nickel and Cobalt are the only pure metals that can be turned into a magnet.
- Magnetic material can be attracted by a magnet but cant be repelled by a magnet. Only two magnets can repel each other. Permanent magnets are always magnetic even when not near other magnets. They produce their own magnetic field. Non-magnetic materials will never be attracted to a magnet
