1. Label the parts of the magnet. A Iron nail B Battery C Wire
2. What is the name of the magnet in the drawing? Electromagnet
3. State what happens when one of the wires is not on the battery. The electromagnet stops working (no current flows, so no magnetic field is produced).
4. Which part of the magnet becomes magnetized? The iron nail (core)
5. State two uses of electromagnets.
i. a. Scrapyard crane for lifting metal
ii. b. Electric doorbell or relay switch
6. What type of magnet is an electromagnet? Temporary magnet
7. List TWO ways to increase the strength of the electromagnet.
- Increase the number of coils (turns of wire) around the core
- Increase the current (e.g., use a higher voltage battery or more batteries in series)
Parent Tip: Review the logic above to help your child master the concept of electromagnet worksheet.
