| Natural Magnet | magnet found in nature |
| Temporary Magnet | keeps its magnetic properties a short time |
| Permanent Magnet | keeps its magnetic properties a long time |
| North Pole | positive pole of a magnet |
| South Pole | negative pole of a magnet |
| Magnetic Field | area around a magnet where magnetism exists |
| Generator | changes mechanical energy to electrical energy |
| Transformer | changes the voltage of electricity |
| Electric Motor | changes electrical energy to mechanical energy |
| Dipole | atom that behaves like a tiny magnet |
| Dynamo | DC generator |
| Alternator | AC generator |
| Stators | stationary armatures in an AC generator |
| Brushes | carry the current in a generator to the wires leading to the external circuit |
| Domains | magnetic regions of dipoles |
| Iron filings | may be used with a magnet to show a magnetic field |
| Poles | of a magnet are the area of greatest attraction and repulsion |
| Electromagnet | you can create one of these with a nail and electricity |
| Curved, Looped wire | current is produced if you move a magnet through this |
| Electricity | an electromagnet shows that you can use this to make magnetism |
| Repel | like poles of magnets do this to each other |
| Attract | unlike poles of magnets to this to each other |
| Induction | this causes a current to flow in a wire WITHOUT touching it |
