| electromagnet | a strong, short-lasting magnet that can be made by inserting iron into a wire coil that is conducting an electric current |
| electromagnetic induction | the creation of electric current when a magnet is moved inside a loop of wire; generators are devices that work using electromagnetic induction. |
| electromagnetic force | the force that exists between electric charges; often described as electrical force or magnetic force depending on how charges interact. |
| generator | a combination of mechanical and electrical systems that converts kinetic energy into electrical energy. |
| magnetic field | an area of magnetic force that surrounds magnetic objects. |
| magnetic north pole | the end of a magnetic object that points toward the geographic north pole of the Earth. |
| magnetic field intensity | the strength of the magnetic field as indicated by the field lines, more lines means more strength |
| magnetic force | a force exerted on a particle or object traveling in a magnetic field. |
| magnetic south pole | the end of a magnetic object that points away from the geographic north pole of the Earth. |
| permanent magnet | a magnetic object that retains its magnetic properties without external influence |
