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 |
