| Term | Definition |
|---|---|
| Magnetism | The force of attraction or repulsion between two magnetic objects. |
| Domain | A microscopic magnetic region composed of a group of atoms whose magnetic fields are aligned. |
| Motor | A device that uses electromagnetism to convert electrical energy to mechanical energy. |
| Generator | A device that uses induction to convert mechanical energy to electrical energy. |
| Transformer | A device that changes one AC potential difference (voltage) to a different AC potential difference (voltage). |
| Electromagnet | A magnet that is created by passing an electric current through a coil of wire. |
| Magnetic Field | A region in which a magnetic force can be detected. |
| Solenoid | A coil of wire that acts like a magnet when a current passes through it. |
| Induction | A current created by the motion of a magnetic field through a coil. |
