- 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.
