  1. 4. One of the two magnetic poles.
  2. 5. A conductor wrapped around an iron core to make an electromagnet.
  3. 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.
  4. 8. A device that provides electrical energy to a circuit.
  5. 9. a non-contact force that can push or pull using an external magnetic field.
  6. 11. The two ends of a magnet where its magnetic field is strongest.
  7. 12. Wire wrapped into loops to help produce a magnetic field.

  1. 1. When two like magnetic poles are pushed away from each other.
  2. 2. an object or material that creates its own persistent magnetic field.
  3. 3. The opposite pole to north.
  4. 7. An instrument that uses a magnetic needle to show direction.
  5. 10. When two unlike magnetic poles are pulled towards each other.
