Chapter 18 Vocabulary Magnet – Any material that attracts iron or materials containing iron Poles – The parts of the magnets where the magnetic effects are strongest Magnetic Force – The force of repulsion or attraction between the poles of magnets Electromagnetism – The interaction between electricity and magnetism Solenoid –A coil of wire that produces a magnetic field when carrying an electric current Electromagnet – A magnet that consists of a solenoid wrapped around an iron core Electric Motor – A device that changes electrical energy into kinetic energy Electromagnetic Induction – The process by which an electric current is produced by a changing magnetic field Generator – A device that uses electromagnetic induction to convert kinetic energy into electrical energy Transformer – A device that increases or decreases the voltage of an alternating current
