Magnetic Materials
Iron, nickel and cobalt are the only pure metals that can be turned into a magnet. These metals are “magnetic materials”.
Properties of magnetic materials
- Magnetic materials, like iron, don’t always act as magnets.
- For example a normal piece of iron won’t attract (pull) or repel (push) another piece of iron.
- But magnetic materials, like iron, are attracted to a magnet if they are close enough to the magnet.
Properties of magnetic materials
- Magnetic materials can be attracted by a magnet, but can’t be repelled by a magnet.
- Only two magnets can repel each other.
- Non-magnetic materials will never be attracted to magnets.
- Permanent magnets are always magnetic, even when they are not near other magnets.
- They produce their own magnetic field.
