Magnet notes
An permanent magnet always has magnetic properties.
Magnets stick to metal but only if they are made with iron or steel.
When magnets pull on each other and stick that we say they attract, when magnets push apart, we say they repel.
Magnets have a north and a south side. They are called poles.
Opposites attract NS, same poles will repel.
Magnets can induce a magnetic field, which mean it can cause magnetic properties in a non magnetic metal item. (ex. nail, paper clip)
Temporary magnetism, is called induced magnetism.
Magnets are surrounded by an invisible magnetic force which acts through space and all non magnetic materials.
The magnetic force acting between magnets decreases as the distance between them increases.
Magnets only stick to other magnets.
