| magnetic force | the force a magnetic field exerts on a magnet, on a ferromagnetic material, or on a moving electric charge |
| magnetic pole | a region on a magnet where the force produced by the magnet is strongest |
| magnetic field | a field in a region that exerts magnetic forces, a field produced by magnets, by changing electric fields, or by moving chargers |
| magnetosphere | the area surrounding Earth that is influenced by Earth's magnetic field |
| magnetic domain | a region that has a large number of atoms with aligned magnetic fields |
| ferromagnetic material | a material that can be magnetized because it contains magnetic domain |
| electromagnetic force | a force asociated with charged particles, which has two aspects, electric force and magnetic force |
| solenoid | a coil of current-carrying wire that produces a magnetic field |
| electromagnet | a solenoid with a ferromagnetic core |
| galvanometer | a device that uses an elctromagnet to measure small amounts of current |
| 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 the relative motion of a coil of wire with respect to a magnetic field |
| transformer | a device that increases or decreases the voltage two linked AC circuits |
| turbine | a device with fanlike blades that turn when pushed, for example, by water or steam |
