| Solenoid | a coil of wire that produces a magnetic field when carrying and electric current |
| Generator | device that uses electromagnetic induction to convert kinetic energy into electrical energy |
| Magnet | any material that attracts iron or materials containing iron |
| Poles | the parts of a magnet where the magnetic effects are strongest |
| Electromagnetic induction | process by which an electric current is produced by changing magnetic field |
| Electromagnetism | the interaction between electricity and magnetism |
| Transformer | increases or decreases the voltage of an alternating current |
| Electromagnet | a magnet that consists of a solenoid wraped around an iron core |
| Magnetic force | the force between magnets depends on how the poles of the magnets line up (opposites attract) |
