Magnets
- Magnets have two poles, the north pole
and the south pole. If a magnet is freely
suspended the north point will point to the
north pole of the world.
- Steel, nickel, iron and cobalt are the four magnetic materials
- To test whether on not a material is a magnet
see if it attracts one end and repels on the
other
- Magnetic materials contain small
molecular magnets called domains
- If a magnetic material is not a
magnet it's domains point in
differnet directions
