| A | B | 
| 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 | 
| galvanometer | a device that uses an electromagnet 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 rotating a coil of wire in a magnetic field | 
| transformer | a device that increases or decreases the voltage and current of two linked AC circuits | 
| turbine | a device with fanlike blades that turn when pushed by water or steam |
