Across
- 4. One of the two magnetic poles.
- 5. A conductor wrapped around an iron core to make an electromagnet.
- 6. a type of magnet that can be switched on and off and is classified as a temporary magnet. It used electricity to produce a magnetic field.

- 9. a non-contact force that can push or pull using an external magnetic field.
- 11. The two ends of a magnet where its magnetic field is strongest.
- 12. Wire wrapped into loops to help produce a magnetic field.
Down
- 1. When two like magnetic poles are pushed away from each other.
- 2. an object or material that creates its own persistent magnetic field.
- 3. The opposite pole to north.
- 7. An instrument that uses a magnetic needle to show direction.
