| magnetic force | the force a magnet exerts on another magnet, on iron or a similar metal, or on moving charges |
| magnetic pole | regions where the magnet's force is strongest |
| magnetic field | surrounds a magnet and can exert magnetic forces |
| magnetosphere | the area surrounding Earth that is influenced by the magnetic field |
| magnetic domain | a region that has a very large number of atoms with aligned magnetic fields |
| ferromagnetic material | material that can be magnetized because it contains magnetic domains, ex: iron |
| electromagnetic force | the electricity and magnetism which are different aspects of a single force |
| solenoid | a coil of current-carrying wire that produces a magnetic field |
| electromagnet | a solenoid with a ferromagnetic core |
| electric motor | a device that uses an electromagnet to turn an axle |
| electromagnetic induction | the process of generating a current by moving an electrical conductor relative to a magnetic field |
| generator | a device that converts mechanical energy into electrical energy by rotating a coil of wire in a magnetic field |
